The multifaceted concept of impulsivity implies that different impulsivity aspects, mediated by
different neural processes, influence behavior at different levels. The nucleus accumbens …

Rationale Latent inhibition (LI), namely, poorer performance on a learning task involving a
previously pre-exposed non-reinforced stimulus, is disrupted in the rat by the dopamine (DA) …

The ability to behave in a flexible manner is an executive function mediated in part by
different regions of the prefrontal cortex. The present study investigated the role of two major …

Dysfunction of goal-directed behaviors under stressful or pathological conditions results in
impaired decision-making and loss of flexibility of thoughts and behaviors, which underlie …

The nucleus accumbens can be subdivided into at least two anatomically distinct
subregions: a dorsolateral 'core'and a ventromedial 'shell', and this distinction may extend to …

The nature of the primary symptoms of schizophrenia and our lack of knowledge of its
underlying cause both contribute to the difficulty of generating convincing animal models of …

Organisms exposed to a stimulus which has no significant consequences, show
subsequently latent inhibition (LI), namely, retarded conditioning to this stimulus. LI is …

The effects of electrolytic lesions of the medial prefrontal cortex (mPFC) or its subregions
were investigated on two cognitive tests that may have relevance to the behavioral …

Latent inhibition is a measure of retarded conditioning to a previously presented
nonreinforced stimulus that is impaired in schizophrenic patients and in rats treated with …

Latent inhibition (LI) consists in a retardation of conditioning seen when to-be-conditioned
stimulus is first presented a number of times without other consequence. Disruption of LI has …
