Making Working Memory Work: A Computational Model of Learning in the Prefrontal Cortex and Basal Ganglia

Abstract: Abstract:The prefrontal cortex has long been thought to subserve both working memory (the holding of information online for processing) and "executive" functions (deciding how to manipulate working memory and perform processing). Although many computational models of working memory have been developed, the mechanistic basis of executive function remains elusive, often amounting to a homunculus. This paper presents an attempt to deconstruct this homunculus through powerful learning mechanisms that allow a compu… Show more

“…In their model, the amygdala codes for stimulus intensity, but not valence. Their model is supported by findings that dopamine-dependent reward mechanisms are activated in motor and habit learning in rats and can be disrupted by striatal lesions,57 findings with patients with Parkinson’s disease,58 healthy control subjects given medications that affect the dopamine system,59 and computational modeling 52,54…”

“…O’Reilly, Frank, and colleagues5254 have proposed a model for the interaction of the basal ganglia and OFC in reward learning. Their model is based on previous models that had been developed to explain the role of the basal ganglia in motor control, “[s]pecifically in the motor domain, various authors suggest that the basal ganglia are specialized to selectively facilitate adaptive motor actions, while suppressing others 55.…”
