Neural systems analysis of decision making during goal-directed navigation; Video

Adaptive decisions during goal-directed navigation depend on a hierarchy of systems and cellular level interactions in the brain. This video demonstrates on a basic level, the relative involvement of the hippocampus, the dopamine system, and the ventral and dorsal (medial and lateral) striatum during a simple food search task on a laboratory maze. Particular attention is paid to the relative contributions of these brain areas while the rat initially learns about the environment, makes choices in a familiar environment, how decisions are adjusted when familiar conditions change.
