Extinction of responding maintained by timeout from avoidance. (1/658)

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. (2/658)

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)

Psychophysics of remembering. (3/658)

We present a new model of remembering in the context of conditional discrimination. For procedures such as delayed matching to sample, the effect of the sample stimuli at the time of remembering is represented by a pair of Thurstonian (normal) distributions of effective stimulus values. The critical assumption of the model is that, based on prior experience, each effective stimulus value is associated with a ratio of reinforcers obtained for previous correct choices of the comparison stimuli. That ratio determines the choice that is made on the basis of the matching law. The standard deviations of the distributions are assumed to increase with increasing retention-interval duration, and the distance between their means is assumed to be a function of other factors that influence overall difficulty of the discrimination. It is a behavioral model in that choice is determined by its reinforcement history. The model predicts that the biasing effects of the reinforcer differential increase with decreasing discriminability and with increasing retention-interval duration. Data from several conditions using a delayed matching-to-sample procedure with pigeons support the predictions.  (+info)

The role of the response-reinforcer relation in delay-of-reinforcement effects. (4/658)

The role of the response-reinforcer relation in maintaining operant behavior under conditions of delayed reinforcement was investigated by using a two-operandum (i.e., two-key) procedure with pigeons. Responding on one key was reinforced under a tandem variable-interval differential-reinforcement-of-other-behavior (tandem VI DRO) schedule. The schedule defined a resetting unsignaled delay-of-reinforcement procedure in that a response was required when the interfood interval of the VI schedule lapsed, but further responding during the DRO component on either key reset the time interval. This ensured a fixed delay duration between any response and reinforcement. Responding on another key, physically identical to the first one except for spatial location, otherwise was without consequence. The location of the key correlated with the delay-of-reinforcement procedure varied between sessions according to a semirandom sequence. Differences in response rates between the two keys were greater, with proportionally higher rates on the key correlated with the delay-of-reinforcement procedure, the longer the delay-of-reinforcement procedure remained correlated with the same key. Differences in responding on the two keys also increased within individual sessions. These results suggest that the response-reinforcer relation is the primary determinant of responding when responding is acquired and maintained with delayed reinforcement.  (+info)

Echolocation behaviour and prey-capture success in foraging bats: laboratory and field experiments on Myotis daubentonii. (5/658)

During prey-capture attempts, many echolocating bats emit a 'terminal buzz', when pulse repetition rate is increased and pulse duration and interpulse interval are shortened. The buzz is followed by a silent interval (the post-buzz pause). We investigated whether variation in the structure of the terminal buzz, and the calls and silent periods following it, may provide information about whether the capture attempt was successful and about the size of prey detected - detail that is valuable in studies of habitat use and energetics. We studied the trawling bat Myotis daubentonii. The time between the first call of the approach phase and the end of the terminal phase was not related to prey size in the laboratory. The last portion of the terminal buzz (buzz II) was shortened or omitted during aborted capture attempts. Both in the laboratory and in the field, the mean interpulse interval immediately after the terminal buzz (post-buzz interpulse interval) was longer in successful captures than in unsuccessful attempts. In the laboratory, the post-buzz pause was longer after successful captures than for unsuccessful attempts, and the minimum frequency of the first search-phase call emitted after the buzz (Fmin) was higher than that of the last such call prior to the buzz. These effects were not apparent in field data. Both in the laboratory (85%) and in the field (74%), significant discrimination between successful and unsuccessful capture attempts was possible when the duration of the post-buzz pause, post-buzz interpulse interval and Fmin were entered into a discriminant analysis. Thus, variation in the echolocation calls of bats during prey-capture attempts can reveal substantial information about capture success and prey size.  (+info)

Calibration of vector navigation in desert ants. (6/658)

Desert ants (Cataglyphis sp.) monitor their position relative to the nest using a form of dead reckoning [1] [2] [3] known as path integration (PI) [4]. They do this with a sun compass and an odometer to update an accumulator that records their current position [1]. Ants can use PI to return to the nest [2] [3]. Here, we report that desert ants, like honeybees [5] and hamsters [6], can also use PI to approach a previously visited food source. To navigate to a goal using only PI information, a forager must recall a previous state of the accumulator specifying the goal, and compare it with the accumulator's current state [4]. The comparison - essentially vector subtraction - gives the direction to the goal. This whole process, which we call vector navigation, was found to be calibrated at recognised sites, such as the nest and a familiar feeder, throughout the life of a forager. If a forager was trained around a one-way circuit in which the result of PI on the return route did not match the result on the outward route, calibration caused the ant's trajectories to be misdirected. We propose a model of vector navigation to suggest how calibration could produce such trajectories.  (+info)

The chemical defense ecology of marine unicellular plankton: constraints, mechanisms, and impacts. (7/658)

The activities of unicellular microbes dominate the ecology of the marine environment, but the chemical signals that determine behavioral interactions are poorly known. In particular, chemical signals between microbial predators and prey contribute to food selection or avoidance and to defense, factors that probably affect trophic structure and such large-scale features as algal blooms. Using defense as an example, I consider physical constraints on the transmission of chemical information, and strategies and mechanisms that microbes might use to send chemical signals. Chemical signals in a low Re, viscosity-dominated physical environment are transferred by molecular diffusion and laminar advection, and may be perceived at nanomolar levels or lower. Events that occur on small temporal and physical scales in the "near-field" of prey are likely to play a role in cell-cell interactions. On the basis of cost-benefit optimization and the need for rapid activation, I suggest that microbial defense system strategies might be highly dynamic. These strategies include compartmented and activated reactions, utilizing both pulsed release of dissolved signals and contact-activated signals at the cell surface. Bioluminescence and extrusome discharge are two visible manifestations of rapidly activated microbial defenses that may serve as models for other chemical reactions as yet undetected due to the technical problems of measuring transient chemical gradients around single cells. As an example, I detail an algal dimethylsulfoniopropionate (DMSP) cleavage reaction that appears to deter protozoan feeding and explore it as a possible model for a rapidly activated, short-range chemical defense system. Although the exploration of chemical interactions among planktonic microbes is in its infancy, ecological models from macroorganisms provide useful hints of the complexity likely to be found.  (+info)

Olfactory foraging by Antarctic procellariiform seabirds: life at high Reynolds numbers. (8/658)

Antarctic procellariiform seabirds forage over vast stretches of open ocean in search of patchily distributed prey resources. These seabirds are unique in that most species have anatomically well-developed olfactory systems and are thought to have an excellent sense of smell. Results from controlled experiments performed at sea near South Georgia Island in the South Atlantic indicate that different species of procellariiforms are sensitive to a variety of scented compounds associated with their primary prey. These include krill-related odors (pyrazines and trimethylamine) as well as odors more closely associated with phytoplankton (dimethyl sulfide, DMS). Data collected in the context of global climatic regulation suggest that at least one of these odors (DMS) tends to be associated with predictable bathymetry, including upwelling zones and seamounts. Such odor features are not ephemeral but can be present for days or weeks. I suggest that procellariiforms foraging over vast distances may be able to recognize these features reflected in the olfactory landscape over the ocean. On the large scale, such features may aid seabirds in navigation or in locating profitable foraging grounds. Once in a profitable foraging area, procellariiforms may use olfactory cues on a small scale to assist them in locating prey patches.  (+info)

When presented with a light cue followed by food, some rats simply approach the foodcup (Nonorienters), while others first orient to the light in addition to displaying the food-cup approach behavior (Orienters). Cue-directed orienting may reflect enhanced attentional and/or emotional processing of the cue, suggesting divergent natures of cue-information processing in Orienters and Nonorienters. The current studies investigate how differences in cue processing might manifest in appetitive memory retrieval and updating using a paradigm developed to persistently attenuate fear responses (Retrieval-extinction paradigm; Monfils et al., 2009). First, we examined whether the retrieval-extinction paradigm could attenuate appetitive responses in Orienters and Nonorienters. Next, we investigated if the appetitive memory could be updated using reversal learning (fear conditioning) during the reconsolidation window (as opposed to repeated unreinforced trials, i.e., extinction). Both extinction and new fear
Obesity is a major public health problem in modern society. Appetitive behavior has been proposed to be partially driven by unconscious decision-making processes and thus, targeting the unconscious cognitive processes related to eating behavior is essential to develop strategies for overweight individuals and obese patients. Here, we presented food pictures below the threshold of awareness to healthy male volunteers and examined neural activity related to appetitive behavior using magnetoencephalography. We found that, among participants who did not recognize food pictures during the experiment, an index of heart rate variability assessed by electrocardiography (low-frequency component power/high-frequency component power ratio, LF/HF) just after picture presentation was increased compared with that just before presentation, and the increase in LF/HF was negatively associated with the score for cognitive restraint of food intake ...

This study provides genetic evidence that MMP-9 is required for appetitive, but not aversive, instrumental learning. Furthermore, it shows that MMP-9 activity in the CeA is crucial for this type of learning. First, we demonstrate that unconditional genetic ablation of MMP-9 impairs three kinds of appetitively motivated conditioning (i.e., place preference and discriminative learning in the IntelliCages both with sweetened water and tap water as the reinforcement). On the other hand, lack of MMP-9 does not impair place avoidance and aversively motivated discrimination in the same apparatus. Next, we show that MMP-9 is present in the amygdala and enzymatically active at the excitatory synapses in the CeA; moreover, its activity is greatly enhanced in the CeA specifically after the appetitive training. Finally, by blocking extracellular MMP-9 activity by nanoparticle-based release of its inhibitor, recombinant TIMP-1, we reveal that local MMP-9 activity in the CeA is crucial for the appetitive, but ...

Galanin is a 29/30-amino acid long neuropeptide that has been implicated in many physiological and behavioral functions. Previous research has shown that i.c.v. administration of galanin strongly stimulates food intake in sated rats when food is freely available, but fails to stimulate this consumption when an operant response requirement is present. Using fixed ratio (FR) schedules, we sought to further clarify galanins role in motivated behavior by administering galanin i.c.v. to rats working on fixed ratio schedules requiring either a low work condition (FR1) or higher work conditions (FR , 1) to obtain a 0.2% saccharin reward. Rats in the FR , 1 group were assigned to either an FR3, FR5 or FR7 schedule of reinforcement. The rate of reinforcement decreased for only the FR , 1 group as compared to saline controls. Furthermore, injections of GalR1 receptor agonist M617 led to a similar, marginally significant decrease in the number of reinforcers received in the FR , 1 condition, but a ...
In this study, we demonstrate striking similarities in the activity of amygdala neurons during conditioned appetitive and aversive emotional arousal and strong relationships between neuronal activity in the amygdala and blood pressure-a measure of arousal which is sensitive to lesions of the amygdala in both appetitive (24) and aversive (21, 22) settings. Cells with increases in activity during one CS+ were more likely than would be expected by chance to show the same response to the other oppositely valenced CS+, and the same was true of CS− elicited decreases. Neuronal activity was also more similar than expected by chance during the appetitive and aversive conditioned stimuli when the activity of all recorded cells was considered together. Additionally, the activity of neurons with similar directions of change in firing during conditioned appetitive and aversive stimuli (same cells) was more likely to be correlated with blood pressure than the rest of the population. Same cells were also ...
Previous studies have shown that appetitive motivation enhances episodic memory formation via a network including the substantia nigra / ventral tegmental area (SN/VTA), striatum and hippocampus. This functional magnetic resonance imaging (fMRI) study now contrasted the impact of aversive and appetitive motivation on episodic long-term memory. Cue pictures predicted monetary reward or punishment in alternating experimental blocks. One day later, episodic memory for the cue pictures was tested. We also investigated how the neural processing of appetitive and aversive motivation and episodic memory were modulated by dopaminergic mechanisms. To that end, participants were selected on the basis of their genotype for a variable number of tandem repeat polymorphism of the dopamine transporter (DAT) gene. The resulting groups were carefully matched for the 5-HTTLPR polymorphism of the serotonin transporter gene. Recognition memory for cues from both motivational categories was enhanced in participants

This article seeks to understand the e-journal search patterns of STM (science, technology, and medicine) researchers from the French academic network by studying how researchers seek, read, and use articles on the ScienceDirect platform. The methodology combines two approaches. The first approach is quantitative and is based on statistical data concerning search activities on ScienceDirect between January 2008 and April 2009. The second approach is qualitative and is based on semi-directed interviews of researchers authorized to access ScienceDirect. The researchers information-seeking activities on ScienceDirect follow two complementary usage logics. On the one hand, they follow search and discovery itineraries, and, on the other hand, they implement continuous and recurrent access mechanisms. In both cases, the researchers searching behaviours on ScienceDirect are similar to their behaviours on the Web. This study concerns a previously unpublished large-scale analysis of STM searching behaviours.

The single training session appetitive LTM assay provides a unique advantage for the study of memory consolidation because one can manipulate the brain immediately after training during the initial period of memory formation. In contrast, 10 cycles of aversive spaced training takes 150 min to complete (Tully et al., 1994), and therefore one cannot perturb neural processing during this period without also interfering with acquisition. Using cold-shock anesthesia, we found that appetitive memory is quickly, and perhaps entirely, consolidated to anesthesia-resistant forms within 2 h after training.. Previous work in flies suggests that cold shock-resistant memory can be broken into two independent components, ARM that depends on the rsh gene and is resistant to CXM and LTM that is unaffected by rsh and is sensitive to CXM (Tully et al., 1994; Isabel et al., 2004). Feeding flies CXM disrupted appetitive LTM and produced a statistically significant defect 6 h after training, suggesting that protein ...

TY - JOUR. T1 - The hypothalamus and the neurobiology of drug seeking. AU - Marchant, Nathan J.. AU - Zayra Millan, E.. AU - McNally, Gavan P.. PY - 2012/2/1. Y1 - 2012/2/1. N2 - The hypothalamus is a neural structure critical for expression of motivated behaviours that ensure survival of the individual and the species. It is a heterogeneous structure, generally recognised to have four distinct regions in the rostrocaudal axis (preoptic, supraoptic, tuberal and mammillary). The tuberal hypothalamus in particular has been implicated in the neural control of appetitive motivation, including feeding and drug seeking. Here we review the role of the tuberal hypothalamus in appetitive motivation. First, we review evidence that different regions of the hypothalamus exert opposing control over feeding. We then review evidence that a similar bi-directional regulation characterises hypothalamic contributions to drug seeking and reward seeking. Lateral regions of the dorsal tuberal hypothalamus are ...
Two strains homozygous for Snfor, SnForGly/Gly and SnForSer/Ser, were each initiated from 15 homozygote founder couples taken from the laboratory-reared polymorphic population and genotyped after reproduction. For the whole-body analysis, 30 fourth-instar larvae per strain were tested. For the brain analysis, 64 fourth-instar larvae per strain were tested. In this condition, the brains (deutocerebrum) were pooled in groups of eight (i.e. eight replicates for each population). The live larvae were retrieved from the artificial diet at the fourth-instar stadium, a stage usually reached during behavioural testing protocol, and immediately frozen in liquid nitrogen and stored at −80°C until RNA extraction.. Total RNA was extracted from whole larvae using TRI Reagent (Sigma-Aldrich). The brains were dissected in the RA1 buffer and total RNA was extracted using the NucleoSpin RNA XS kit (Macherey Nagel). In both conditions, a DNase treatment (DNase I recombinant, Roche) was also performed. The ...
This article introduces a formalization of the dynamics between sensorimotor interaction and homeostasis, integrated in a single architecture to learn object affordances of consummatory behaviors. We also describe the principles necessary to learn grounded knowledge in the context of an agent and its surrounding environment, which we use to investigate the constraints imposed by the agents internal dynamics and the environment. This is tested with an embodied, situated robot, in a simulated environment, yielding results that support this formalization. Furthermore, we show that this methodology allows learned affordances to be dynamically redefined, depending on object similarity, resource availability, and the rhythms of the agents internal physiology. For example, if a resource becomes increasingly scarce, the value assigned by the agent to its related effect increases accordingly, encouraging a more active behavioral strategy to maintain physiological stability. Experimental results also ...
For the sows themselves two behaviors that theyre very strongly motivated to do are things we need to consider.. The first one is they are very strongly motivated to feed.. Its an evolutionary necessity for animals and its still in our modern sows.. We feed them levels which are perfectly adequate for good health and good performance but from the sows point of view theyre not very satisfying.. Theyre used to actually having bulkier diets and more gut fill and a small amount of concentrated food will leave them unsatisfied.. In that situation two things can happen.. If they can show a normal type of food searching behavior, as they can for example in straw systems in the UK, then theyll spend time doing that.. If you put them in a situation where they cant show those behaviors then you start to see more problems.. If theyre in gestation stalls those behaviors turn into things like the bar biting which has been highlighted so much by animal welfare organizations.. If theyre in group ...

During olfactory learning in fruit flies, dopaminergic neurons assign value to odor representations in the mushroom body Kenyon cells. Here we identify a class of downstream glutamatergic mushroom body output neurons (MBONs) called M4/6, or MBON-β2β2a, MBON-β2mp, and MBON-γ5β2a, whose dendritic fields overlap with dopaminergic neuron projections in the tips of the β, β, and γ lobes. This anatomy and their odor tuning suggests that M4/6 neurons pool odor-driven Kenyon cell synaptic outputs. Like that of mushroom body neurons, M4/6 output is required for expression of appetitive and aversive memory performance. Moreover, appetitive and aversive olfactory conditioning bidirectionally alters the relative odor-drive of M4β neurons (MBON-β2mp). Direct block of M4/6 neurons in naive flies mimics appetitive conditioning, being sufficient to convert odor-driven avoidance into approach, while optogenetically activating these neurons induces avoidance behavior. We therefore propose that drive to

The article below may contain offensive and/or incorrect content.. Theories of functioning in the medial prefrontal cortex are distinct across appetitively and aversively motivated procedures. In the appetitive domain, it is argued that the medial prefrontal cortex is important for producing adaptive behavior when circumstances change. This view advocates a role for this region in using higher-order information to bias performance appropriate to that circumstance. Conversely, literature born out of aversive studies has led to the theory that the prelimbic region of the medial prefrontal cortex is necessary for the expression of conditioned fear, whereas the infralimbic region is necessary for a decrease in responding following extinction. Here, the argument is that these regions are primed to increase or decrease fear responses and that this tendency is gated by subcortical inputs. However, we believe the data from aversive studies can be explained by a supraordinate role for the medial ...
