Abstract
We have previously developed a simple hard wired neural network which investigates the role of the dorsolateral prefrontal cortex, the ventrolateral prefrontal cortex and the Anterior Cingulate Gyrus, together with their associated basal ganglia-thalamocortical loops, in solving the classical delayed response task, Delayed visual matching and the Wisconsin Card Sorting Task. This was done by constraining the model to some of the known connectivity within these areas. Here an extension of this model is described which includes reinforcement of the Hebbian type as a mechanism to learn features as working memories. Lesions applied to the hard wired model are also discussed with respect to the deficits observed in various kind of patients while performing those tasks.
