Welcome to this Henry Stewart talk devoted to the anatomical organization of the basal ganglia. My name is Andre Parent. I am professor of neuroscience at the University Laval in Quebec City, Canada.

The aim of this presentation is to provide an overall review of the basal ganglia organization, based on that I gathered from the current literature, as well as a result of our own morphological studies of the basal ganglia undertaken in humans and non-human primates. The talk is divided into four distinct parts. The first part concerns the overall organization of the basal ganglia. A special attention will be paid to the dual basal ganglia model, which is widely used to explain the functional organization of the sets of subcortical structures in both health and disease. The second part summarizes the result of our own single-axon tracing studies of the various basal ganglia components in monkeys. The third part is devoted to the presence of dopaminergic neurons within the primate striatum. The last part of the presentation reviews evidence for the persistence of neurogenesis in the striatum of adult primates.
