Functional imaging of stimulus convergence in amygdalar neurons during Pavlovian fear conditioning.
5 Jul 2009 
BACKGROUND: Associative conditioning is a ubiquitous form of learning throughout the animal kingdom and fear conditioning is one of the most widely researched models for studying its neurobiological basis. Fear conditioning is also considered a ...

Affective modulation of conditioned eyeblinks.
2 Jul 2009 
Affective states are known to modulate reflexive actions. Aversive states potentiate defensive reflexes while appetitive states diminish them. The present study examined whether the same holds for associatively learned defensive eyeblinks to mild, ...

30 Jun 2009 Estrogen receptor activation has been shown to reduce body weight and produce a conditioned reduction in food intake in male rats that is putatively mediated by estradiol's suggested aversive effects. Evidence has shown that the selective estrogen ...

29 Jun 2009 The delta opioid system is involved in the behavioral effects of various drugs of abuse. However, only a few studies have focused on the possible interactions between the opioid system and the effects of 3,4-methylenedioxymethamphetamine (MDMA). In ...

Learning about associations: evidence for a hierarchical account of occasion setting.
29 Jun 2009 In 2 experiments rats were trained on a switching discrimination, with 4 occasion setters, A, B, C, and D and 2 target stimuli, x and y. When signaled either by A or by B, x was reinforced with food and y was not, whereas when signaled either by C ...

Spontaneous recovery of excitation and inhibition.
29 Jun 2009 In two conditioned suppression experiments with rats as subjects, the authors examined two classes of accounts of spontaneous recovery of excitation and inhibition. One view suggests that spontaneous recovery occurs due to greater temporal ...

Attentional and error-correcting associative mechanisms in classical conditioning.
29 Jun 2009 R. A. Rescorla (2000, Rescorla, 2001, Rescorla, 2002) reported that the associative changes undergone by 2 conditioned stimuli that are reinforced or not reinforced in compound depend on their initial associations. The results contradict the ...

Resolution of conflict between goal-directed actions: outcome encoding and neural control processes.
29 Jun 2009 According to O-R theory of instrumental learning, incongruent biconditional discriminations should be impossible to solve in a goal-directed manner because the event acting as the outcome of one response also acts as a discriminative stimulus for an ...

Potentiation and overshadowing in Pavlovian fear conditioning.
29 Jun 2009 The present experiments addressed a fundamental discrepancy in the Pavlovian conditioning literature concerning responding to a target cue following compound reinforced training with another cue of higher salience. Experiment 1 identified one ...

The loss of latent inhibition across compound conditioning.
29 Jun 2009 Six experiments used a magazine approach paradigm with rats to investigate latent inhibition (LI). Experiment 1 found that compound conditioning did not increase evidence for LI, in contrast to predictions from acquisition-deficit models that are ...
