Lesions of the OFC had no effect on the sensitivity of instrumental performance to a reduction in outcome value, but were effective in disrupting the influence of pavlovian outcome expectancies over instrumental response selection. Furthermore, although OFC lesions left intact the performance of previously acquired conditioned approach behavior, they were found to disrupt the rats ability to appropriately adjust their performance to meet a reduction in the underlying pavlovian contingency. These findings provide new clues regarding the role of the OFC in predictive learning.. Several previous studies have shown that OFC lesions disrupt the control that expected outcome value exerts on previously acquired responses (Gallagher et al., 1999; Izquierdo et al., 2004; Pickens et al., 2003, 2005). In each of these studies, however, performance of the target response was likely to have depended, at least in part, on pavlovian learning (Roberts, 2006), supporting the view that the OFC plays an important ...
Optimal control problems have been addressed by methods of dynamic programming (Bellmann 1957) which is a large scientific area in its own right (not to be discussed here). Trial-and-error learning has roots in Psychology, especially Classical Conditioning and instrumental conditioning. As a consequence, the first stream (optimal control) was from the beginning governed by highly algorithmical/mathematical approaches, whereas for the second stream (animal learning) it took much longer for the first, still more qualitative, mathematical models to be developed (see, for example, the Rescorla-Wagner Model). Optimal control and instrumental conditioning deal with closed-loop control problems. However, Classical Conditioning deals with a prediction-only problem because the response of the animal does not influence the experiment, or - in more general terms - does not influence the environment. A good short summary relating algorithmic approaches to real classical conditioning experiments is given by ...

Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning. In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. Such a recovery of "lost" behaviors can be observed within a variety of domains, and the recovery of lost human memories is often of particular interest. For a mathematical model for spontaneous recovery see Further Reading. Spontaneous recovery is associated with the learning process called classical conditioning, in which an organism learns to associate a neutral stimulus with a stimulus which produces an unconditioned response, such that the previously neutral stimulus comes to produce its own response, which is usually similar to that produced by the unconditioned stimulus. Although aspects of classical conditioning had been noted by previous scholars, the first experimental analysis of the process was done by Ivan ...

Learning is a process by which we integrate new knowledge generated as a result of experiences. The product of such experiences is converted into memories stored in our brain. There is basically no learning without memories.. There are essentially two ways in which learning occurs: one is called classical conditioning and the other instrumental conditioning. Both ways modify brain structure and brain chemistry, but they do so with varying degree of awareness or self-control. Classical conditioning pertains to situations in which we tend to respond automatically, based on the severity or repetition of a stimulus. The amygdala is involved in regulating many of our autonomic, fight or flight type responses. For instrumental conditioning, more brain structures appear to take an active role in encoding and reinforcing a learned behavior. For instance when we learn driving, the repetition or rehearsal of that behavior will involve the perceptual and motor systems as well as the frontal lobes. As the ...
We want to establish intero-interoceptive fear conditioning with a differential conditioning paradigm. We want to make use of real interoceptive conditioned stimuli (CS): A low respiratory load (1.43 kPa/l/s) resistance and small infusions of pentagastrin (0.2 g/ kg) will be used as CS. CO2-enriched air is used as unconditioned stimulus (UCS). To rule out possible procedural effects also a placebo injection and placebo resistance is included in this study. The experiment consists of two parts, acquisition and test. During acquisition we want to establish conditioning (linking CS to the UCS). During the test part only the CS is given without the UCS ...

A pavlovian learning experiment in lowly sea slugs has provided new clues to how we remember our childhood. The findings, reported in tomorrows Science, are the strongest evidence yet for the long-suspected role of long-term potentiation (LTP), a physiological process that jacks up the response of certain neurons to incoming signals.. When a neuron equipped for LTP receives two signals in rapid succession, the second one triggers the LTP process, in which special channels open up and allow calcium ions to flow into the neuron. The calcium triggers biochemical reactions that alter the neurons sensitivity so that a repeat of that signal will produce a heightened response. LTP seemed to be a logical way to encode memories, because it provides a means for neurons to associate simultaneous events, and it reinforces the neurons response to those stimuli when they occur again. Researchers have worked for decades to understand LTP and to establish its link to memory, but they were hampered by the ...

In a third variation of the experiment, after the destruction had been carried by the method of alternation to such a degree as to be already appreciable, four or five applications of the positive stimulus in succession were sufficient to reverse this effect, re-establishing the inhibition.. Another method of experiment for the demonstration of negative induction was employed by Dr. Prorokov, who made use of an old observation that the positive conditioned reflex response which was evoked second in an experiment frequently showed the greatest secretory effect. This was most probably owing to an increased excitability of the alimentary centre following on the first reinforcement with the unconditioned reflex; on this account a recently established, but not yet quite stable, inhibitory stimulus is frequently disturbed when applied in an experiment immediately after the first application of the unconditioned stimulus, the reflex being partially dis-inhibited. When several positive conditioned ...

This dataset includes pupil size response (PSR), skin conductance response(SCR), electrocardiogram (ECG) and respiration measurements for each of 20 healthy unmedicated participants (8 males and 12 females aged 22.8+/-3.3 years) participating in a classical (Pavlovian) discriminant delay fear conditioning task. (One additional participant in the initial sample in Korn et al. (2017) - but who did not finish the experiment and was not included into the analysis - is not contained in this dataset.) The acquisition data is separated into two sessions which were recorded consecutively with a break of approximately 5 min. CS consist of two sine tones with constant frequency (220 Hz or 440 Hz, 50-ms onset and offset ramp) and last for 6.5 s. US is a 0.5 s train of electric square pulses delivered with a constant current stimulator (Digitimer DS7A, Digitimer, Welwyn Garden City, UK) on participants dominant forearm through a pin-cathode/ring-anode configuration. SOA betwen the CS and US is 6 s. The ITI is
The cellular mechanisms supporting plasticity during memory consolidation have been a subject of considerable interest. De novo protein and mRNA synthesis in several brain areas are critical, and more recently protein degradation, mediated by the ubiquitin-proteasome system (UPS), has been shown to be important. Previous work clearly establishes a relationship between protein synthesis and protein degradation in the amygdala, but it is unclear whether cortical mechanisms of memory consolidation are similar to those in the amygdala. Recent work demonstrating a critical role for prefrontal cortex (PFC) in the acquisition and consolidation of fear memory allows us to address this question. Here we use a PFC-dependent fear conditioning protocol to determine whether UPS mediated protein degradation is necessary for memory consolidation in PFC. Groups of rats were trained with auditory delay or trace fear conditioning and sacrificed 60 min after training. PFC tissue was then analyzed to quantify the amount
Adult Lepidoptera are capable of associative learning. This helps them to forage flowers or to find suitable oviposition sites. Larval learning has never been seriously considered because they have limited foraging capabilities and usually depend on adults as concerns their food choices. We tested if Spodoptera littoralis larvae can learn to associate an odor with a tastant using a new classical conditioning paradigm. Groups of larvae were exposed to an unconditioned stimulus (US: fructose or quinine mixed with agar) paired with a conditioned stimulus (CS: hexanol, geraniol or pentyl acetate) in a petri dish. Their reaction to CS was subsequently tested in a petri dish at different time intervals after conditioning. Trained larvae showed a significant preference or avoidance to CS when paired with US depending on the reinforcer used. The training was more efficient when larvae were given a choice between an area where CS-US was paired and an area with no CS (or another odor). In these ...

Fear memories, here defined as learned associations between a stimulus and a physiological fear reaction, are formed through fear conditioning. In animals, fear memories, present in the lateral amygdala, undergo reconsolidation after recall. Moreover, this reconsolidation process can be disrupted both pharmacologically and behaviourally, resulting in a reduced fear response to the stimulus. This thesis examines the attenuation of fear memories by disrupting reconsolidation in humans, using measures of both the central and peripheral nervous system activity. Serotonergic and dopaminergic genes have previously been tied to both fear conditioning and anxiety disorders, where fear conditioning mechanisms are important. In order to evaluate the possible role of fear memory reconsolidation mechanims in the effect on fear and anxiety by these genes, this thesis also compare the reconsolidation disruption effect between different serotonergic and dopaminergic genotypes.. Study I examined the ...

MicroRNAs (miRNAs) and other classes of short non-coding RNAs regulate essential processes in the development and function of the nervous system. Regulation of miRNAs by neural activity has also been reported. Recently, instances of piwi interacting RNA (piRNA) and endogenous short interfering RNA (esiRNA) mediated modulation of neural physiology have been reported. To better understand the role of miRNAs and other classes of short non-coding RNAs in long term memory (LTM) formation, we have conducted high throughput sequencing on 15-35nt RNAs isolated from heads of Drosophila that have been subjected to aversive olfactory conditioning. We developed genome wide profiles of miRNA, piRNA, and esiRNA, and tested for differential expression following conditioning. We find that 5 miRNAs exhibit significant regulation in the conditioned group. We identify several esiRNA generating loci within genes required for olfactory LTM formation. Our data reveal that an intron of the multiple wing hairs (mwh) ...

Even at level 8, the neurogenesis-fear conditioning story was one of the more convincing arguments of new neuron functionality. With this study by Drew et al. we may soon be jumping for joy as we appear to be graduating to level 9.. The contribution of adult neurogenesis to contextual fear conditioning was greatest when mice were only given a brief training experience - mice lacking adult neurogenesis showed reduced fear of a context where they previously received a single footshock during a brief (3 min) exploration session. With longer exposures to the context, or additional footshocks, neurogenesis-deficient mice showed normal memory. This finding could be explained by the fact that young neurons have a lower threshold for synaptic plasticity, allowing them to encode fleeting experiences that would be forgotten if left to mature neurons.. So, brief training protocols may now likely be my first choice, at least when using mice. In fact, the only times I have observed contextual fear memory ...
In Kamins blocking effect the conditioning of an association between two stimuli, a conditioned stimulus (CS) and an unconditioned stimulus (US) is impaired if, during the conditioning process, the CS is presented together with a second CS that has already been associated with the unconditioned stimulus. For example, an agent (such as a mouse in the figure) is exposed to a light (the first conditioned stimulus, CS1), together with food (the unconditioned stimulus, US). After repeated pairings of CS1 and US, the agent salivates when the light comes on (conditioned response, CR). Then, there are more conditioning trials, this time with the light (CS1) and a tone (CS2) together with the US. Now, when tested, the agent does not salivate to the tone (CS2). In other words, an association between the tone CS2 and the US has been "blocked" because the CS1-US association already exists. This effect was most famously explained by the Rescorla-Wagner model. The model says, essentially, that if one CS ...
PhD, University of Michgian Associate Professor of Psychiatry and Molecular & Behavioral Neuroscience Institute We are a behavioral neuroscience lab focused on understanding both the behavioral and neurobiological factors that contribute to individual differences in reward learning and susceptibility to addiction. We are interested in the psychological mechanisms that underlie and influence appetitive Pavlovian learning and the neural circuitry involved in these processes.
The aim of this project is to create fear conditioning paradigm within which the relative strengths of various novel pharmacological and behavioral interventions can be tested. These interventions are intended to reduce the fearfulness associated with fear conditioning by blocking a memory process known as reconsolidation. In fear conditioning, a conditioned stimulus (CS) is paired with an aversive unconditioned stimulus (US) such as an electric shock, until presentation of the CS alone comes to elicit a fear conditioned response (CR). The investigators hypothesize that by using a more highly prepared CS (i.e. video of spiders); more sensitive subjects (individuals with stronger acquired CRs); and additional experimental probes for the presence of the latent CR, the investigators may develop a normal human paradigm that is not plagued by previously observed floor effects (i.e. intervention is 100% effective), within which both the established techniques of propranolol and delayed extinction ...

Of the elements that represent a single stimulus at a given moment, some may be in state A1, some in state A2, and some in state I. When a stimulus first appears, some of its elements jump from inactivity I to primary activity A1. From the A1 state they gradually decay to A2, and finally back to I. Element activity can only change in this way; in particular, elements in A2 cannot go directly back to A1. If the elements of both the CS and the US are in the A1 state at the same time, an association is learned between the two stimuli. This means that if, at a later time, the CS is presented ahead of the US, and some CS elements enter A1, these elements will activate some US elements. However, US elements activated indirectly in this way only get boosted to the A2 state. (This can be thought of the CS arousing a memory of the US, which will not be as strong as the real thing.) With repeated CS-US trials, more and more elements are associated, and more and more US elements go to A2 when the CS comes ...
