Differential effects of inactivation of the orbitofrontal cortex on strategy set-shifting and reversal learning.

26 Nov 2007 Different subregions of the rodent prefrontal cortex (PFC) mediate dissociable types of behavioral flexibility. For example, lesions of the medial or orbitofrontal (OFC) regions of the PFC impair extradimensional shifts and reversal learning, ...

Effects of rat medial prefrontal cortex lesions on olfactory serial reversal and delayed alternation tasks.

7 Nov 2007 When reward reinforcement in a two-choice discrimination task is regularly changed from one stimulus to another immediately after one learning acquisition session, the learning efficiency of a rat increases as if the rat has come to recognize this ...

A reversal theory analysis of psychological responses during sports injury rehabilitation.

30 Oct 2007 CONTEXT: Few studies have examined psychological and emotional processes in injury rehabilitation from a longitudinal, theoretically framed perspective. OBJECTIVE: This study explored the applicability of Reversal Theory to examine these processes. ...

Serial reversal learning and the evolution of behavioral flexibility in three species of North American corvids (Gymnorhinus cyanocephalus, Nucifraga columbiana, Aphelocoma californica).

30 Oct 2007 In serial reversal learning, subjects learn to respond differentially to 2 stimuli. When the task is fully acquired, reward contingencies are reversed, requiring the subject to relearn the altered associations. This alternation of acquisition and ...

Spontaneous recovery after reversal and partial reinforcement.

30 Oct 2007 Six experiments used magazine approach in rat subjects to explore changes with time in responding for stimuli brought to a common moderate level of performance through acquisition or extinction. They found no evidence for increases with time in ...

Lesions of rat infralimbic cortex result in disrupted retardation but normal summation test performance following training on a Pavlovian conditioned inhibition procedure.

24 Oct 2007 The prefrontal cortex has a well-established role in the inhibition of inappropriate responding. Converging evidence implicates the infralimbic (IL) region of the rat medial prefrontal cortex (MPFC) in the maintenance of extinction [Quirk et al. ...

Dissociable effects of selective 5-HT2A and 5-HT2C receptor antagonists on serial spatial reversal learning in rats.

22 Oct 2007 Serotonin (5-hydroxytryptamine, or 5-HT) is strongly implicated in the ability to shift behavior in response to changing stimulus-reward contingencies. However, there is little information on the contribution of different 5-HT receptors in reversal ...

Acute tryptophan depletion in healthy volunteers enhances punishment prediction but does not affect reward prediction.

15 Oct 2007 Central serotonin (5-HT) has been implicated in emotional and behavioral control processes for many decades, but its precise contribution is not well understood. We used the acute tryptophan depletion procedure in young healthy volunteers to test ...

Amygdala tractography predicts functional connectivity and learning during feedback-guided decision-making.

10 Oct 2007 Flexibly adapting behavior in dynamic environments relies on fronto-limbic networks that include the amygdala, orbitofrontal cortex, and striatum. Animal work demonstrates that interactions among these regions are critical for flexible ...

Impairments in timing, temporal memory, and reversal learning linked to neurotoxic regimens of methamphetamine intoxication.

10 Oct 2007 Methamphetamine intoxication has long-term consequences on dopaminergic function and corticostriatal-mediated behaviors in humans and other animals. In order to determine the potential impact on timing and temporal memory, we examined ...
