The concept of locally specialized functions dominates research on higher brain function
and its disorders. Locally specialized functions must be complemented by processes that …

Besides neuroanatomical changes, neuromodulatory mechanisms are also compromised
during aging. Neural network models are suitable tools for exploring the relatively broad and …

The Wisconsin Card Sorting Task (WCST) has been used to assess dysfunction of the
prefrontal cortex and basal ganglia. Previous brain imaging studies have focused on …

Dopamine (DA) depletion in the basal ganglia (BG) of Parkinson's patients gives rise to both
frontal-like and implicit learning impairments. Dopaminergic medication alleviates some …

The basal ganglia play a central role in cognition and are involved in such general functions
as action selection and reinforcement learning. Here, we present a model exploring the …

Recent studies have emphasized the importance of dopamine projections to the prefrontal
cortex (PFC) for working memory (WM) function, although this system has rarely been …

Patients with Parkinson's disease (PD) exhibit impairments in several cognitive functions
similar to those observed in patients with prefrontal cortex (PFC) lesions. The physiological …

A biologically detailed computational model is described of how categorization judgments
become automatic in tasks that depend on procedural learning. The model assumes 2 …

Children of different ages often perseverate, repeating previous behaviors when they are no
longer appropriate, despite appearing to know what they should be doing. Using neural …

This thoroughly, thoughtfully revised edition of a very successful textbook makes the
principles and the details of neural network modeling accessible to cognitive scientists of all …
