Improving social interaction in chronic psychotic using discriminated avoidance ("nagging"): experimental analysis and generalization. (1/2017)

Three social-interaction behaviors of a withdrawn chronic schizophrenic were increased using a discriminated avoidance ("nagging") procedure. The three behaviors were: (a) voice volume loud enough so that two-thirds of his speech was intellibible at a distance of 3m; (b) duration of speech of at least 15 sec; (c) placement of hands and elbows on the armrests of the chair in which he was sitting. "Nagging" consisted of verbal prompts to improve performance when the behaviors did not meet their criteria. A combined withdrawal and multiple-baseline design was used to evaluate the effectiveness of the procedure, and the contingency was sequentially applied to each of the three behaviors in each of four different interactions to determine the degree of stimulus and response generalization. Results indicated that the contingency was the effective element in increasing the patient's appropriate performance, and that there was a high degree of stimulus generalization and a moderate degree of response generalization. After the patient's discharge from the hospital, the durability of improvement across time and setting was determined in followup sessions conducted at a day treatment center and at a residential care home. Volume and duration generalized well to the new settings, while arm placement extinguished immediately.  (+info)

Extinction of responding maintained by timeout from avoidance. (2/2017)

The resistance to extinction of lever pressing maintained by timeout from avoidance was examined. Rats were trained under a concurrent schedule in which responses on one lever postponed shock on a free-operant avoidance (Sidman) schedule (response-shock interval = 30 s) and responses on another lever produced 2 min of signaled timeout from avoidance on a variable-ratio 15 schedule. Following extended training (106 to 363 2-hr sessions), two experiments were conducted. In Experiment 1 two different methods of extinction were compared. In one session, all shocks were omitted, and there was some weakening of avoidance but little change in timeout responding. In another session, responding on the timeout lever was ineffective, and under these conditions timeout responding showed rapid extinction. The within-session patterns produced by extinction manipulations were different than the effects of drugs such as morphine, which also reduces timeout responding. In Experiment 2 shock was omitted for many consecutive sessions. Response rates on the avoidance lever declined relatively rapidly, with noticeable reductions within 5 to 10 sessions. Extinction of the timeout lever response was much slower than extinction of avoidance in all 4 rats, and 2 rats continued responding at baseline levels for more than 20 extinction sessions. These results show that lever pressing maintained by negative reinforcement can be highly resistant to extinction. The persistence of responding on the timeout lever after avoidance extinction is not readily explained by current theories.  (+info)

Blocking a selective association in pigeons. (3/2017)

Experiment 1 demonstrated for the first time a stimulus-reinforcer interaction in pigeons trained with free-operant multiple schedules of reinforcement. Pigeons that treadle pressed in the presence of a tone-light (TL) compound for food exhibited primarily visual stimulus control on a stimulus-element test, whereas pigeons that avoided shock in TL exhibited auditory control. In Experiment 2, this selective association was blocked in pigeons pretrained with the biologically contingency-disadvantage element of the compound (i.e., tone-food or light-shock) before TL training. When this pretraining preceded compound-stimulus training, control was now auditory in pigeons that treadle pressed for food and was visual in pigeons that avoided shock. Previous attempts at blocking this selective association were unsuccessful in pigeons (LoLordo, Jacobs, & Foree, 1982) but were successful in rats (Schindler & Weiss, 1985). Experiment 2 established that selective associations can be blocked in pigeons when the procedures that were effective with rats were systematically replicated. These results further demonstrate the cross-species generality of an associative attentional mechanism involving a biological constraint on learning in species with different dominant sensory systems.  (+info)

Effects of promazine, chlorpromazine, d-amphetamine, and pentobarbital on treadle pressing by pigeons under a signalled shock-postponement schedule. (4/2017)

The effects of promazine on treadle pressing to postpone the presentation of electric shock were studied in three pigeons. The effects of chlorpromazine, d-amphetamine, and pentobarbital were studied in two of these pigeons. Each treadle press postponed electric shock for 20 sec and presentation of a preshock stimulus for 14 sec. Selected doses of both promazine and chlorpromazine increased the rates of treadle pressing in all birds. The response-rate increases produced by promazine and chlorpromazine were due to increased conditional probabilities of treadle pressing both before and during the preshock stimulus. d-Amphetamine (1 and 3 mg/kg) slightly increased responding in one of the birds, but not to the extent that promazine or chlorpromazine did. In the other bird, the 10 mg/kg dose of d-amphetamine increased shock rate but did not change response rate. Some doses of d-amphetamine increased the conditional probabilities of responding both in the absence of the preshock signal and during the preshock signal in both birds. Pentobarbital only decreased response rates and increased shock rates.  (+info)

Improvement by nefiracetam of beta-amyloid-(1-42)-induced learning and memory impairments in rats. (5/2017)

1. We have previously demonstrated that continuous i.c.v. infusion of amyloid beta-peptide (A beta), the major constituent of senile plaques in the brains of patients with Alzheimer's disease, results in learning and memory deficits in rats. 2. In the present study, we investigated the effects of nefiracetam [N-(2,6-dimethylphenyl)-2-(2-oxo-1-pyrrolidinyl) acetamide, DM-9384] on A beta-(1-42)-induced learning and memory deficits in rats. 3. In the A beta-(1-42)-infused rats, spontaneous alternation behaviour in a Y-maze task, spatial reference and working memory in a water maze task, and retention of passive avoidance learning were significantly impaired as compared with A beta-(40-1)-infused control rats. 4. Nefiracetam, at a dose range of 1-10 mg kg(-1), improved learning and memory deficits in the A beta-(1-42)-infused rats when it was administered p.o. 1 h before the behavioural tests. 5. Nefiracetam at a dose of 3 mg kg(-1) p.o. increased the activity of choline acetyltransferase in the hippocampus of A beta-(1-42)-infused rats. 6. Nefiracetam increased dopamine turnover in the cerebral cortex and striatum of A beta-(1-42)-infused rats, but failed to affect the noradrenaline, serotonin and 5-hydroxyindoleacetic acid content. 7. These results suggest that nefiracetam may be useful for the treatment of patients with Alzheimer's disease.  (+info)

Intrahippocampal infusion of interleukin-6 impairs avoidance learning in rats. (6/2017)

AIM: To study the effect of intrahippocampal infusion of interleukin-6 (IL-6) on active avoidance in rats and the possible involvement of nitric oxide (NO). METHODS: Using a shuttle-box model, the effects of bilaterally intrahippocampal infusion of IL-6 3.2, 16, and 80 ng as well as sodium nitroprusside (SNP) 400 ng on active avoidance were studied on d 8 after administration. The levels of nitrite as an index of NO in the hippocampus were detected using a fluorometric assay 24 h after infusion of IL-6 3.2 or 80 ng. RESULTS: IL-6 16 and 80 ng impaired the acquisition performance of active avoidance by prolonging the latency of avoidance in training, but not the retention performance in testing. IL-680 ng and SNP 400 ng also resulted in a marked impairment in acquisition performances by decreasing the rate of avoidance, but not in retention performances. IL-680 ng markedly elevated the nitrite levels from 10.6 +/- 0.7 in control rats to 13.6 +/- 2.0 (nmol/g wet wt) (P < 0.01). IL-6 3.2 ng had no effect on active avoidance nor on nitrite levels. CONCLUSION: Intrahippocampal infusion of IL-6 impaired learning acquisition of active avoidance in rats.  (+info)

Behavioral changes and cholinesterase activity of rats acutely treated with propoxur. (7/2017)

Early assessment of neurological and behavioral effects is extremely valuable for early identification of intoxications because preventive measures can be taken against more severe or chronic toxic consequences. The time course of the effects of an oral dose of the anticholinesterase agent propoxur (8.3 mg/kg) was determined on behaviors displayed in the open-field and during an active avoidance task by rats and on blood and brain cholinesterase activity. Maximum inhibition of blood cholinesterase was observed within 30 min after administration of propoxur. The half-life of enzyme-activity recovery was estimated to be 208.6 min. Peak brain cholinesterase inhibition was also detected between 5 and 30 min of the pesticide administration, but the half-life for enzyme activity recovery was much shorter, in the range of 85 min. Within this same time interval of the enzyme effects, diminished motor and exploratory activities and decreased performance of animals in the active avoidance task were observed. Likewise, behavioral normalization after propoxur followed a time frame similar to that of brain cholinesterase. These data indicate that behavioral changes that occur during intoxication with low oral doses of propoxur may be dissociated from signs characteristic of cholinergic over-stimulation but accompany brain cholinesterase activity inhibition.  (+info)

Modeling geriatric depression in animals: biochemical and behavioral effects of olfactory bulbectomy in young versus aged rats. (8/2017)

Geriatric depression exhibits biological and therapeutic differences relative to early-onset depression. We studied olfactory bulbectomy (OBX), a paradigm that shares major features of human depression, in young versus aged rats to determine mechanisms underlying these differences. Young OBX rats showed locomotor hyperactivity and a loss of passive avoidance and tactile startle. In contrast, aged OBX animals maintained avoidance and startle responses but showed greater locomotor stimulation; the aged group also exhibited decreased grooming and suppressed feeding with novel presentation of chocolate milk, effects which were not seen in young OBX. These behavioral contrasts were accompanied by greater atrophy of the frontal/parietal cortex and midbrain in aged OBX. Serotonin transporter sites were increased in the cortex and hippocampus of young OBX rats, but were decreased in the aged OBX group. Cell signaling cascades also showed age-dependent effects, with increased adenylyl cyclase responses to monoaminergic stimulation in young OBX but no change or a decrease in aged OBX. These data indicate that there are biological distinctions in effects of OBX in young and aged animals, which, if present in geriatric depression, provide a mechanistic basis for differences in biological markers and drug responses. OBX may provide a useful animal model with which to test therapeutic interventions for geriatric depression.  (+info)

The potency of two β-endorphin fragments, des-Tyr1-γ-endorphin (DTγE, βE-(2-17)) and des-enkephalin-γ-endorphin (DEγE, βE-(6-17)) was compared on extinction of pole-jumping avoidance behavior and on retention of a one-trial step-through passive avoidance procedure. Both peptides facilitated the extinction of pole-jumping avoidance behavior and attenuated passive avoidance behavior. The γ-type endorphins exhibited an ... read more inverted U-shaped dose-response curve on passive avoidance behavior but not on extinction of pole-jumping avoidance behavior. DEγE appeared to be approximately three times more potent than DTγE on extinction of pole-jumping avoidance behavior but one hundred times more potent on passive avoidance behavior.

N2 - Although much has been learned about the role of the amygdala in Pavlovian fear conditioning, relatively little is known about an involvement of this structure in more complex aversive learning, such as acquisition of an active avoidance reaction. In the present study, rats with a pretraining injection of the N-methyl-D-aspartate (NMDA) receptor antagonist, 2-amino-S-phosphonopentanoic acid (APV), into the basolateral amygdala (BLA) were found to be impaired in two-way active avoidance learning. During multitrial training in a shuttle box, the APV-injected rats were not different from the controls in sensitivity to shock or in acquisition of freezing to contextual cues. However, APV ...
We investigated the effects of thioperamide, a histamine H3-receptor antagonist, on a scopolamine-induced learning deficit in the step-through passive avoidance test in mice, and on contents of acetylcholine and choline in the brain. In a behavioral study, thioperamide (20 mg/kg) alone slightly ameliorated scopolamine-induced learning deficit, and pretreatment with zolantidine, a histamine H2-receptor antagonist, significantly enhanced the ameliorating effect of thioperamide. This enhanced ameliorating effect of thioperamide was antagonized by pyrilamine, a histamine H1-receptor antagonist and (R)-alpha-methylhistamine, a histamine H3-receptor agonist, suggesting that thioperamide showed the ameliorating effect via histamine H3 receptors and/or histamine H1 receptors. In the biochemical study, thioperamide (20 mg/kg) in combination with zolantidine (20 mg/kg) significantly increased contents of choline in most of brain regions. These findings suggest that there is a close relationship between

The effect of repeated nonreinforced pretraining exposure to the training apparatus on avoidance memory reconsolidation is time dependent and requires NMDAr activation immediately after each preexposure session. A, Left, Bilateral intra-CA1 infusion of AP5 immediately after each preexposure session prevented the decrease in step-down latency caused by repeated nonreinforced exposure to the training environment. Animals were allowed to explore the step-down inhibitory avoidance (SD-IA) TB once daily for 5 min during 5 d and immediately after each session received intra-CA1 infusions of VEH (0.9% saline) or AP5 (5 μg/side).

Morphines effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. Whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. The present study intended to investigate whether administration of morphine can change the expression level of rat hippocampal proteins during learning of a passive avoidance task. A step-through type passive avoidance task was used for the assessment of memory retention. To identify the complex pattern of protein expression induced by morphine, we compared rat hippocampal proteome either in morphine-induced amnesia or in state-dependent learning by two-dimensional gel electerophoresis and combined mass spectrometry (MS and MS/MS). Post-training administration of morphine decreased step-through latency. Pre-test administration of morphine induced state-dependent retrieval of the memory
Individual differences in generalization of aversive value (but not safety information) during human active avoidance learning specifically predict experience of anxiety and intrusive thoughts.

N2 - Post-training administration of opiate antagonists improves retention of recent learning in laboratory animals tested on a variety of tasks. We examined the possibility that this effect of opiate antagonist treatment might be due to release of brain norepinephrine (NE) function from opioid peptide inhibition. The behavioral testing procedure in these experiments consisted of one-trial passive avoidance conditioning. Rats received post-training treatments immediately after the training trial and retention was tested 24 h later. Lesions of the dorsal noradrenergic bundle (DNB) that were induced by 6-hydroxydopamine (6-OHDA) were found to prevent the memory enhancing effect of post-training naloxone administration. The memory enhancing effect of naloxone ...
Both muscarinic antagonists, such as scopolamine, and benzodiazepine receptor (BZR) agonists, such as diazepam, produce a reliable impairment in the performance of one trial passive avoidance. Such deficits are frequently interpreted as drug-induced amnesia. However, these deficits could also result from a learning impairment. The present experiments compared the effects of two BZR agonists, lorazepam (0, 0.125, 0.25, and 0.375 mg/kg, IP) and diazepam (0, 0.78, 1.56, and 3.13 mg/kg, IP) with the effects of two muscarinic antagonists, scopolamine (0, 0.6, 0.8 and 1.0 mg/kg, SC) and atropine (0, 15, 30 and 60 mg/kg, IP) on a multiple trial passive avoidance task. In this procedure, the rats were trained with a 5-min inter-trial interval until a learning criterion was achieved. Retention was assessed 24 h later. This enabled the effects of the drugs on the acquisition and the retention of a passive avoidance response to be dissociated. Both atropine and scopolamine produced a marked impairment in the
Background: Cognitive functions are impaired in patients with liver disease. Bile duct ligation causes cholestasis that impairs liver function. This study investigated the impact of cholestasis progression on the acquisition and retention times in the passive avoidance test and on the locomotor activity of rats. Methods: Cholestasis was induced in male Wistar rats by ligating the main bile duct. Locomotor activity, learning and memory were assessed by the passive avoidance learning test at day 7, day 14, and day 21 post-bile duct ligation. The serum levels of bilirubin, alanine aminotransferase, and alkaline phosphatase were measured. Results: The results showed that acquisition time and locomotor activity were not affected at day 7 and day 14, but they were significantly (P , 0.05) impaired at day 21 post-bile duct ligation compared with the results for the control group. Additionally, memory was significantly impaired on day 7 (P , 0.01), day 14, and day 21 (P , 0.001) compared with the ...
Electric shock is a common stimulus for nociception-research and the most widely used reinforcement in aversive associative learning experiments. Yet, nothing is known about the mechanisms it recruits at the periphery. To help fill this gap, we undertook a genome-wide association analysis using 38 inbred Drosophila melanogaster strains, which avoided shock to varying extents. We identified 514 genes whose expression levels and/or sequences covaried with shock avoidance scores. We independently scrutinized 14 of these genes using mutants, validating the effect of 7 of them on shock avoidance. This emphasizes the value of our candidate gene list as a guide for follow-up research. In addition, by integrating our association results with external protein-protein interaction data we obtained a shock avoidance- associated network of 38 genes. Both this network and the original candidate list contained a substantial number of genes that affect mechanosensory bristles, which are hairlike organs distributed
Under experimental conditions, virtually all behaviors of Caenorhabditis elegans are achieved by combinations of simple locomotion, including forward, reversal movement, turning by deep body bending, and gradual shallow turning. To study how worms regulate these locomotion in response to sensory information, acidic pH avoidance behavior was analyzed by using worm tracking system. In the acidic pH avoidance, we characterized two types of behavioral maneuvers that have similar behavioral sequences in chemotaxis and thermotaxis. A stereotypic reversal-turn-forward sequence of reversal avoidance caused an abrupt random reorientation, and a shallow gradual turn in curve avoidance caused non-random reorientation in a less acidic direction to avoid the acidic pH. Our results suggest that these two maneuvers were each triggered by a distinct threshold pH. A simulation study using the two-distinct-threshold model reproduced the avoidance behavior of the real worm, supporting the presence of the threshold.
Training-induced neuronal activity develops in the mammalian limbic system during discriminative avoidance conditioning. This study explores behaviorally relevant changes in muscarinic ACh receptor binding in 52 rabbits that were trained to one of five stages of conditioned response acquisition. Sixteen naive and 10 animals yoked to criterion performance served as control cases. Upon reaching a particular stage of training, the brains were removed and autoradiographically assayed for 3H-oxotremorine-M binding with 50 nM pirenzepine (OXO-M/PZ) or for 3H-pirenzepine binding in nine limbic thalamic nuclei and cingulate cortex. Specific OXO-M/PZ binding increased in the parvocellular division of the anterodorsal nucleus early in training when the animals were first exposed to pairing of the conditional and unconditional stimuli. Elevated binding in this nucleus was maintained throughout subsequent training. In the parvocellular division of the anteroventral nucleus (AVp), OXO-M/PZ binding ...

Aversiveness of biological sounds has been studied in detail in the context of predator avoidance (Deecke et al., 2002; Tuttle and Ryan, 1981). By contrast, factors influencing aversiveness of other sounds are poorly understood and have only been investigated with respect to stimulus amplitude (Campbell, 1957; Kastelein et al., 2006a), practical applications (Blackshaw et al., 1990; Kastelein et al., 2001; Talling et al., 1998) or the use of sound as a reinforcing stimulus (Campbell and Bloom, 1965). An aversive stimulus is an unpleasant or noxious stimulus, which induces an avoidance response in an animal. Such behavioural responses to sounds are influenced by a variety of psychophysical factors relating to sound perception, the motivational state of an animal and basic learning processes (e.g. habituation, conditioning). Elucidating the role of these factors is not only relevant for animal welfare and conservation (Nowacek et al., 2007) but can also provide answers to fundamental questions of ...

An avoidance response is a response that prevents an aversive stimulus from occurring. It is a kind of negative reinforcement. An avoidance response is a behavior based on the concept that animals will avoid performing behaviors that result in an aversive outcome. This can involve learning through operant conditioning when it is used as a training technique. It is a reaction to undesirable sensations or feedback that leads to avoiding the behavior that is followed by this unpleasant or fear-inducing stimulus. Whether the aversive stimulus is brought on intentionally by another or is naturally occurring, it is adaptive to learn to avoid situations that have previously yielded negative outcomes. A simple example of this is food aversions, or the aversion developed to food that has previously resulted in sickness. Food aversions can also be conditioned using classical conditioning, so that an animal learns to avoid a stimulus previously neutral that has been associated with a negative outcome. This ...
Vasopressin (VP) is axonally distributed in many brain structures, including the ventral hippocampus. Picogram quantities of VP injected into the hippocampus improve the passive avoidance response of rats, presumably by enhancing memory processes. Vasopressin is metabolized by the brain tissue into shorter peptides, such as [pGlu4r,Cyt6]VP(4 9[ and [pGIu4,Cyt6,]VP(4 8), which preserve ... read more the behavioral activity but lose the peripheral activities of the parent hormone. Using brain slices, we investigated whether VP or VP(4 8) affects excitatory postsynaptic potentials (EPSPs) and/or membrane responses to depolarization in neurons of the CA 1 /subiculum of the ventral hippocampus. The EPSPs were evoked by stimulating the stratum radiatum of the CAI field; the membrane responses were elicited by current injections. Exposure of slices for 15 min to 0.1 nM solution of these peptides resulted in an increase in the amplitude and slope of the EPSPs in 21 neurons (67%) tested. No consistent ...

N2 - Levels of c-fos mRNA expression in mouse cerebral cortex and hippocampus at different stages of footshock escape and avoidance learning were studied by Northern hydridization. In the first series of experiments a mouse was presented with 30 electric footshock daily in a chamber where it could escape from the floor by jumping on the safe platform attached to the wall. A large increase in c-fos mRNA level in the cerebral cortex and hippocampus was observed during the first day of training. Mice that were trained for 9 consecutive days and acquired a footshock escape reaction showed no elevation of c-fos expression in the brain as compared to the quiet control group. In the second series of experiments the levels of c-fos expression were compared in individual mice trained to avoid the footshock by ...
The principles of operant conditioning have taught us to recognize how certain coping techniques can reward, and therefore continue anxiety disorders. Two similar coping strategies for dealing with anxiety symptoms are called avoidance and escape.
The effects of scopolamine (2.0 mg/kg) and d-amphetamine (3.0 mg/kg) on one-way, shuttle and inhibitory avoidance performance were evaluated in 3 strains of mice (A/J, DBA/2J and C57BL/6J) and their 6 reciprocal F1 hybrids. In the saline condition, intermediate inheritance was observed in the inhibitory task, complete dominance for superior avoidance in the one-way task, and hybrid superiority in the shuttle situation. Administration of d-amphetamine disrupted inhibitory performance in all strains. In the shuttle task no amphetamine effect was observed in C57BL/6J mice, while improvement was seen in A/J and DBA/2J mice, as well as in all the hybrid crosses. No drug effect was seen in the one-way task. As with d-amphetamine, scopolamine disrupted performance in the inhibitory task among the inbreds, but had negligible effects in the hybrids. In the shuttle task, only the A/J mice exhibited improved performance, while a small decline in response rate was seen in one-way avoidance. Results were ...
The present study investigated the potential sex differences in repeated aripiprazole (ARI) treatment-induced behavioral sensitization from adolescence to adulthood, and to determine whether ARI sensitization can be transferred to olanzapine (OLZ) and/or clozapine (CLZ) using the conditioned avoidance response (CAR) and phencyclidine-induced (PCP) hyperlocomotion tests of antipsychotic activity. Male and female Sprague-Dawley adolescence rats (P46) were first treated with ARI (10 mg/kg) for 5 consecutive days (P46-50) and tested for avoidance response and ARI-induced inhibition of PCP-induced hyperlocomotion. After they became adults (|P68), rats were challenged with ARI (1.5 mg/kg, sc) (P70), OLZ (0.5 mg/kg, sc; P73), CLZ (5 mg/kg, sc; P76) and again with ARI (1.5 mg/kg, sc; P84) and tested for avoidance response and ARI-induced inhibition of PCP-induced hyperlocomotion again. During the drug treatment period in adolescence, repeated ARI treatment suppressed avoidance response, inhibited the PCP
Reforms that focus on the methodological procedures of the acquisition process are only partial remedies because they do not address incentives to deviate from sound practices. Weapons acquisition is a complicated enterprise, complete with unintended incentives that encourage moving programs forward by delaying testing and employing other problematic practices. These incentives stem from several factors. For example, the different participants in the acquisition process impose conflicting demands on weapon programs so that their purpose transcends just filling voids in military capability. Also, the budget process forces funding decisions to be made well in advance of program decisions, which encourages undue optimism about program risks and costs. Finally, DOD program managers short tenures and limitations in experience and training can foster a short-term focus and put them at a disadvantage with their industry counterparts ...

Abstract: Pattern avoidance for permutations has been extensively studied, and has been generalized to vincular patterns, where certain elements can be required to be adjacent. In addition, cyclic permutations, i.e., permutations written in a circle rather than a line, have been frequently studied, including in the context of pattern avoidance. We investigate vincular pattern avoidance on cyclic permutations. In particular, we enumerate many avoidance classes of sets of vincular patterns of length 3, including a complete enumeration for all single patterns of length 3. Furthermore, we enumerate many avoidance classes of vincular patterns of length 4, in which the Catalan numbers appear numerous times. We then study more generally whether sets of vincular patterns of an arbitrary length $k$ can be avoided for arbitrarily long cyclic permutations, in particular investigating the boundary cases of minimal unavoidable sets and maximal avoidable sets ...

The collision avoidance warning system is an emerging technology designed to assist drivers in avoiding red-light running (RLR) collisions at intersections. The aim of this paper is to evaluate the effect of auditory warning information on collision avoidance behaviors in the RLR pre-crash scenarios and further to examine the casual relationships among the relevant factors. A driving-simulator-based experiment was designed and conducted with 50 participants. The data from the experiments were analyzed by approaches of ANOVA and structural equation modeling (SEM). The collisions avoidance related variables were measured in terms of brake reaction time (BRT), maximum deceleration and lane deviation in this study. It was found that the collision avoidance warning system can result in smaller collision rates compared to the without-warning condition and lead to shorter reaction times, larger maximum deceleration and less lane deviation. Furthermore, the SEM analysis illustrate that the audio warning
Evidence shows that cardiovascular system disease (CHD) may be the most common results of hypertension. (CHD). In line with the blood circulation pressure (BP) cutoff of 140/90?mm?Hg for hypertension, seeing that defined with the seventh survey from the Joint Country wide Committee on Avoidance, Recognition, Evaluation, and Treatment of Great BLOOD CIRCULATION PRESSURE (JNC 7) [1], more than 65 million adult Us citizens, or approximately 1 / 4 from the American people, have got hypertension [2]. The survey from the INTERHEART research regarding 52 countries all around the globe demonstrated that H-1152 dihydrochloride manufacture hypertension conferred a larger adjusted relative threat of severe myocardial infarction than diabetes [3]. Among people aged 40 to 90 years, each 20/10?mm?Hg rise in BP doubles the chance of fatal coronary occasions [4]. Reviews of national research conducted in a variety of countries in THE UNITED STATES, Asia, and Africa suggest that hypertension is normally highly ...

We present a multi scale approach for automating the image acquisition process for an computerized virus diagnostic application. Our methods are designed to mimic the methodology used by virus TEM experts manually operating the microscope. The methods decrease the search area considerably. In addition we present a segmentation method for virus-like particles based on local intensity information and PCA. This method makes no assumption regarding shape which is vital since many viruses are highly pleomorphic, i.e., have different shapes. The only input parameter used is the approximate virus thickness, which is a conserved feature within a virus species.. ...

Here is an aspect to consider - Only one person showed, he was late, he was unprepared, the other person didnt show, and had to be reminded, a week later, that you were supposed to talk.. Now, that might not be indicative of a company in trouble, but, clearly, we can safely say their recruiting and talent acquisition process is dysfunctional.. What is the purpose of the recruiting process? To identify and bring on board the best talent possible.. If the process for identifying the right people for the company is a complete crap-show of a mess, what are the odds that they are employing the best people and the best fits for the company? This company is going to be filled with employees gathered through this mess of a process. Chances are they will have missed or turned-off some of the best candidates out there. Chances are they will have hired people who are either not good workers or possibly not even technically competent. You cant take a process that clearly doesnt work and expect it to get ...

University of Washington law professor Anita Ramasastry comments on the recent release of records known as the Paradise Papers, which reveal the identities of thousands of individuals and corporations using offshore jurisdictions as a tax avoidance strategy. Ramasastry argues that while such actions may in many cases be legal, they are also unethical. She points out that if we focus on the harm of tax avoidance to society, rather than how it is legally defined, then we can see that it contributes to growing inequality and increases tax burdens on resident taxpayers who cannot change their citizenship or move their money.

TY - JOUR. T1 - Intracranial self-stimulation facilitates active-avoidance retention and induces expression of c-Fos and Nurr1 in rat brain memory systems. AU - Aldavert-Vera, Laura. AU - Huguet, Gemma. AU - Costa-Miserachs, David. AU - Ortiz, Sandra Pena de. AU - Kádár, Elisabeth. AU - Morgado-Bernal, Ignacio. AU - Segura-Torres, Pilar. PY - 2013/8/1. Y1 - 2013/8/1. N2 - Intracranial self-stimulation (ICSS), a special form of deep brain stimulation in which subjects self-administered electrical stimulation in brain reward areas as the lateral hypothalamus, facilitates learning and memory in a wide variety of tasks. Assuming that ICSS improves learning and memory increasing the activation of memory-related brain areas, the present work examined whether rats receiving an ICSS treatment immediately after the acquisition session of a two-way active avoidance conditioning (TWAA) show both an improved retention and a pattern of increased c-Fos and Nurr1 protein expression in the amygdala, ...
Description: In the conditioned taste aversion test, rats are given two water bottles from which to drink. One is filled with plain water and the other is filled with water to which a small amount of saccharin or sucrose has been added. After a conditioning period, the rats are injected with either a test drug or a saline solution. The rats are returned to their cages and observed to determine whether they avoid the water bottle filled with sweet-tasting water, which would suggest a learned aversion to the solution, i.e., they associated the sweet-tasting water with a negative reaction (e.g., gastrointestinal malaise) that was actually caused by the injected drug. Purpose: Conditioned taste aversion is a useful test for determining whether a drug causes gastrointestinal side effects ...
The amygdala is strongly implicated in learning under emotionally charged settings such as fear. An inhibitory avoidance paradigm was used by Alkire and Nathan in which rats were placed in a lighted chamber facing a dark tunnel, which they normally prefer to enter. However, entrance into the dark area was negatively reinforced by electrical shock; rats quickly learned to avoid entering the dark tunnel and remained in the nonpreferred but safe lighted environment. When retested the next day, the rats continued to avoid entering the dark tunnel; their memory retention latency (i.e. , time to enter the dark tunnel) was very long, indicating that they remember being shocked. If a low concentration of sevoflurane was administered during the initial training period, the animals quickly entered the dark tunnel the following day, i.e. , sevoflurane prevented avoidance learning. However, after bilateral lesion of the basolateral amygdala, rats exhibited equally long memory retention latencies ...
Although the terms taste avoidance and taste aversion are often used interchangeably, studies with rats indicate they are not necessarily synonymous. Aversion is defined as a strong dislike or disinclination[4] and avoidance is defined as stopping oneself from doing.[5] The difference is that in avoidance, the organism is controlling its behavioural responses. Taste avoidance and taste aversion can at times go hand in hand, but they cannot be looked at or be defined the same way.. Studies on rats to determine how they react to different tasting liquids and injections indicate this difference. Scientists measured the facial and somatic reactions of rats after exposure to a flavored solution (sucrose or salt) which do not induce abnormal feelings. However, immediately after the rat ingests the solution, the rat is injected with a drug that induces nausea. The rat subsequently expresses a disgust reaction towards the solution, seen by mouth gaping. This is a Pavlovian conditioned ...
Background and Objective: Lipolysaccharide (LPS) is a large molecule isolated from bacteria such as the enterobacteriaceae family with a negative effect on memory and learning through disturbing the balance of free radicals and creating oxidative stress conditions. In this study, we evaluated the effect of quercetin on oxidative stress and LPS-induced memory impairment in the rat. Materials and Methods: Male rats (n=40) were randomly divided into 5 groups: control, control under treatment with quercetin at a dose of 50 mg/kg, LPS, and LPS groups treated with quercetin at doses of 10 or 50 mg/kg. For induction of inflammation, LPS dissolved in normal saline (500 μg/kg) was injected intraperitoneally. After one week, the passive avoidance behavior was tested in the shuttle box and hippocampal homogenate was prepared. Acetylcholinesterase (AChE) activity and lipid peroxidation (malondialdehyde, MDA) were measured using specific kits. Data were analyzed by SPSS software (version 16). Results: Step
In aposematism a prey species use bright colours, often combined with a black contrasting pattern, to signal unprofitability as prey to potential predators. Although there are several different hypotheses about the presence of these internally contrasting patterns, there is little experimental evidence of any beneficial effects. In this thesis I have used bird predators and artificial prey signals to investigate if the contrasting internal patterns in warning displays may have evolved to increase signal efficacy, especially regarding the speed of avoidance learning. In paper I the relative importance of colour and pattern in avoidance learning was studied. The conclusion was that birds primarily attend to colour, not pattern, when learning the discrimination, which was further supported by the results in paper II-IV, all suggesting a secondary role of patterns. In paper II I show that predators may to some degree use patterns for discrimination, if they convey important information about prey ...
Heterozygous mutations of the human FOXP2 transcription factor gene cause the best-described examples of monogenic speech and language disorders. Acquisition of proficient spoken language involves auditory-guided vocal learning, a specialized form of sensory-motor association learning. The impact of etiological Foxp2 mutations on learning of auditory-motor associations in mammals has not been determined yet. Here, we directly assess this type of learning using a newly developed conditioned avoidance paradigm in a shuttle-box for mice. We show striking deficits in mice heterozygous for either of two different Foxp2 mutations previously implicated in human speech disorders. Both mutations cause delays in acquiring new motor skills. The magnitude of impairments in association learning, however, depends on the nature of the mutation. Mice with a missense mutation in the DNA-binding domain are able to learn, but at a much slower rate than wild type animals, while mice carrying an early nonsense mutation

TY - JOUR. T1 - Perinatal diazepam exposure. T2 - Behavioral and neurochemical consequences. AU - Lauer, Julie A.. AU - Adams, Perrie M.. AU - Johnson, Kenneth M.. PY - 1987/1/1. Y1 - 1987/1/1. N2 - In the present study the effects of perinatal diazepam (DZP) exposure on behavior and benzodiazepine binding site characteristics in offspring were investigated. Pregnant F344 rats were treated during the last trimester of gestation with vehicle or diazepam (3 mg/kg, 5 mg/kg, or 10 mg/kg). Lactating dams were similarly treated on postnatal days 1-7. Both prenatal and postnatal exposure to diazepam resulted in significant effects on the acquisition and extinction of active avoidance behavior measured postweaning. The number of trials to extinction of one-way active avoidance behavior was significantly greater in offspring exposed gestationally to 3 mg/kg and 10 mg/kg diazepam and postnatally to 10 mg/kg diazepam. The mean response latencies for all diazepam treated groups were significantly shorter ...

The aim of the present work was to shed light on the role played by the isoprenoid/cholesterol biosynthetic pathway in the modulation of emotional reactivity and memory consolidation in rodents through the inhibition of the key and rate-limiting enzyme 3-hydroxy 3-methylglutaryl Coenzyme A reductase (HMGR) both in vivo and in vitro with simvastatin. Three-month-old male Wistar rats treated for 21 days with simvastatin or vehicle were tested in the social interaction, elevated plus-maze, and inhibitory avoidance tasks; after behavioral testing, the amygdala, hippocampus, prefrontal cortex, dorsal, and ventral striatum were dissected out for biochemical assays. In order to delve deeper into the molecular mechanisms underlying the observed effects, primary rat hippocampal neurons were used. Our results show that HMGR inhibition by simvastatin induces anxiogenic-like effects in the social interaction but not in the elevated plus-maze test, and improves memory consolidation in the inhibitory ...

Ablation of NK1 receptor bearing neurons in the nucleus of the solitary tract blunts cardiovascular reflexes in awake rats.. Abdala AP, Schoorlemmer GH, Colombari E.. Brain Res 1119(1):165-173, 2006.. Cardiovascular function is largely controlled by the nucleus of the tractus solitarius (NTS). This work focuses on the baroreflex, cardiopulmonary chemoreflex, and arterial chemoreflex. Rats were injected with either 20 nl of 2 µM SP-SAP (Cat. #IT-07) into the subpostremal NTS, or 200 nl into the subpostremal and commissural NTS. Saporin (Cat. #PR-01) was used as a control. It was established that NK-1 receptor-expressing neurons in the NTS are critical for these reflexes..

The dorsal anterior cingulate (adACC) and dorsal medial prefrontal cortex (dmPFC) play a central role in the discrimination and appraisal of threatening stimuli. Yet, little is known about what specific features of threatening situations recruit these regions and how avoidance may modulate appraisal and activation through prevention of aversive events. In this investigation, thirty healthy adults underwent functional neuroimaging while completing an avoidance task in which responses to an Avoidable CS+ threat prevented delivery of an aversive stimulus, but not to an Unavoidable CS+ threat. Extinction testing was also completed where CSs were presented without aversive stimulus delivery and an opportunity to avoid. The Avoidable CS+ relative to the Unavoidable CS+ was associated with reductions in ratings of negative valence, fear, and US expectancy and activation. Greater regional activation was consistently observed to the Unavoidable CS+ during avoidance, which declined during extinction. Individuals
RESULTS: A deficit in avoidance learning and higher corticosterone level were observed in learned helplessness rats. SYG significantly reduced this deficit and reversed the corticosterone alteration. CMS induced significant reduction of sucrose intake in the sucrose preference test, an increased latency to feed in the novelty-suppressed feeding test and an increased immobility time in the forced swim test as compared to the control. It was also found that BDNF and TrkB levels were decreased in CMS model. Chronic treatment of SYG significantly suppressed the behavioral changes and up-regulated the BDNF signal pathway in the hippocampus ...

Writing in the Journal of Immunology, US and Australian scientists have now described the effect of administration of an antagonist of the receptor for the complement activation product, C5a, in animal models of Alzheimers disease. Oral administration of PMX205 in drinking water for 2-3 months resulted in substantial reductions in disease markers such as fibrillar amyloid deposits and activated glia in two mouse models of Alzheimers disease. The reduction in pathological markers correlated with improved performance in a passive avoidance task in Tg2576 mice. In 3xTg mice, PMX205 also significantly reduced hyperphosphorylated tau.. PMX205 is a cyclic hexapeptide derivative that was developed by Promics as a second generation C5a receptor antagonist for the treatment of inflammatory disorders, including inflammatory bowel disease. An earlier compound, PMX53, was found to be well tolerated in phase I clinical trials for rheumatoid arthritis and psoriasis.. The new study shows for the first time ...
Prey face a conflict between acquiring energy and avoiding predators and use both direct and indirect cues to assess predation risk. Illumination, an indirect cue, influences nocturnal rodent foraging behaviour. New Zealand holds no native rodent species but has introduced mice (Mus musculus) that severely impair native biodiversity. We used Giving-Up Densities (GUDs) and observations of foraging frequency and duration to assess if artificial light induces risk avoidance behaviour in mice and could limit their activity. We found both captive (wild strain) mice in outdoor pens and wild mice within a pest fenced sanctuary (Maungatautari, New Zealand) displayed avoidance behaviour in response to illumination. In captivity, total foraging effort was similar across lit and unlit pens but mice displayed a strong preference for removing seeds from dark control areas (mean: 15.33 SD: +/-11.64 per 3.5 hours) over illuminated areas (2.00 +/-3.44). Wild mice also removed fewer seeds from illuminated areas (0.42 +/
On a behavioral level, treated mice out-performed controls on several tests of memory and also out-performed controls on a passive avoidance test ,which relies on memory of punishment.. In terms of brain anatomy there were notable differences in the thickness of the cortex of the brain, particularly in the hippocampus, which participates in memory formation and recall. With respect to the main culprit in Alzheimers disease - ß amyloid - the amount of this protein decreased in treated mice, both inside and outside the brain cells. Also, the pathways that breakdown and remove ß amyloid were more active in the brains of probiotic-treated AD mice.. All in all, the results of this study suggest that probiotics may restore the parts of the brain responsible for memory function, counteract the typical morphological alterations of AD, and significantly reduce the amount of ß amyloid in the brain.. ...

High-resolution x-ray micro-tomography is used for imaging of solid materials at micrometer scale in 3D. Our goal is to implement nondestructive techniques to quantify properties in the interior of solid objects, including information on their 3D geometries, which supports modeling of the fluid dynamics into the pore space of the host object. The micro-tomography data acquisition process generates large data sets that are often difficult to handle with adequate performance when using current standard computing and image processing algorithms. We propose an efficient set of algorithms to filter, segment and extract features from stacks of image slices of porous media. The first step tunes scale parameters to the filtering algorithm, then it reduces artifacts using a fast anisotropic filter applied to the image stack, which smoothes homogeneous regions while preserving borders. Next, the volume is partitioned using statistical region merging, exploiting the intensity similarities of each segment. ...

Although GSA officials say the agencys Networx contracting vehicles have put significant dents in the federal governments telecommunications bills, a GAO study says the road to those savings wasnt nearly as smooth as it could have been.. The Government Accountability Office said complex acquisition processes and weaknesses in project planning contributed to delays transitioning to Networx from the GSAs old FTS2001 contracts, resulting in cost increases and missed savings for federal users.. According to the GAO study, under Networx, federal agencies tended to transition easier items first to demonstrate progress, before they turned to work on items such as data networks and international services that needed longer lead times. As a result of the delays, it said, GSAs estimated cost to complete the transition increased by $66.4 million, 44 percent over the baseline estimate..

If there is a cylindrical obstacle of width w, and the obstacle can be placed at location (x,y) where y varies between y1 and y2, then the resulting obstacle is most simply represented as a single normal distribution with mean=(x,y) and with XX variance of w^2 and YY variance of ((y2-y1)*w)^2. Avoid obstacles checks for overlap between the MOG of the robot location and that of the obstacle. If any member pair ((i,j) with i in robot pos MOG and j in obstacle MOG) has means within 1m of each other, then overlap is calculated.The 1M comes from the CNL 1m parameter used for obstacle avoidance. overlap is calculated using the Bhattacharya measure, and the distribution resulting from this is the sensed positioned of the obstacle. The calculation of obstacle avoidance is as done in the Avoid_Obstacles process ...
