Hippocampal lesions in rhesus monkeys disrupt emotional responses but not reinforcer devaluation effects.

9 Jan 2008 BACKGROUND: Although the role of the hippocampus in emotional behavior has long been recognized, the extent to which the hippocampus plays a role in the regulation and expression of emotion in rhesus monkeys has not been systematically explored. ...

Procedural learning and cognitive flexibility in a mouse model of restricted, repetitive behaviour.

3 Jan 2008 Restricted, repetitive behaviours (e.g., stereotypies, compulsions, rituals) in neurodevelopmental disorders have been linked to alterations in cortico-basal ganglia circuitry. Cognitive processes mediated by this circuitry (e.g., procedural ...

The cerebellum is involved in reward-based reversal learning.

30 Dec 2007 The cerebellum has recently been discussed in terms of a possible involvement in reward-based associative learning. To clarify the cerebellar contribution, eight patients with focal vascular lesions of the cerebellum and a group of 24 healthy ...

Reversal learning as a neuropsychological indicator for the neuropathology of obsessive compulsive disorder? A behavioral study.

30 Dec 2007 A dysfunction of the fronto-striatal loop has been associated with obsessive-compulsive disorder (OCD). Functional imaging studies suggest that reversal learning is affected by deficits in fronto-striatal brain areas and thus should be impaired in ...

Graded effects of number of inserted letters in superset priming.

30 Dec 2007 Three masked priming experiments investigated the effects of target word length and number of inserted letters on superset priming, where irrelevant letters are added to targets to form prime stimuli (e.g., tanble-table). Effects of one, two, three, ...

A role for set in the control of automatic spatial response activation.

30 Dec 2007 Spatial stimulus-response (S-R) compatibility effects are widely assumed to reflect the automatic activation of a spatial response by the spatial attributes of a stimulus. The experiments reported here investigate the role of the participant's set ...

Effects of varying the experimental design of a cognitive control paradigm on behavioral and functional imaging outcome measures.

30 Dec 2007 Abstract A number of experimental techniques are commonly used within the field of functional neuroimaging to measure successive cognitive processes within a single trial. This study evaluated three experimental techniques to assess the ...

Evidence of temporal cortical dysfunction in rhesus monkeys following chronic cocaine self-administration.

17 Dec 2007 Cocaine abusers show impaired performance on cognitive tasks that engage prefrontal cortex. These deficits may contribute to impaired control and relapse in abusers. Understanding the neuronal substrates that lead to these deficits requires animal ...

Discriminative control of variability: effects of successive stimulus reversals.

Dec 2007 A growing body of evidence suggests that behavioral variability can come under control of discriminative stimuli. The present experiment further examined discriminative control of variability in a novel way by using the discrimination-reversal ...

Dopamine gene predicts the brain's response to dopaminergic drug.

29 Nov 2007 Dopamine is critical for reward-based decision making, yet dopaminergic drugs can have opposite effects in different individuals. This apparent discrepancy can be accounted for by hypothesizing an 'inverted-U' relationship, whereby the effect of ...
