Over the past few decades, it became evident that the basal ganglia is involved in cognitive as well as motor processes, including motor control, conditioning, working memory, and sequence learning. Systems-levels models attempt to explain what kinds of computations are employed by the basal ganglia. It is argued that the basal ganglia integrates information from different structures, such as the prefrontal cortex and hippocampus, and decides on which motor response to execute. Learning such motor processes depends on dopamine phasic signals. Similar kinds of processes seem to hold true in the cognitive domain. In this talk, I will discuss recent computational models of the basal ganglia and relate them to neuropsychological studies (e.g., Parkinson's disease).
