Title: Basal Ganglia Loops with the Cerebral Cortex and Cerebellum: Circuits for Movement, Cognition and Affect

Abstract: Parkinson’s Disease, Huntington’s Disease, Attention Deficit-Hyperactivity Disorder, Tourette’s Syndrome and Obsessive-Compulsive Disorder are all thought to involve basal ganglia dysfunction. How can dysfunction at one site result in motor, cognitive and affective disorders? We have taken a multi-disciplinary approach to explore this question in non-human primates. We used micro-injections of neurochemicals to evoke transient motor and nonmotor disorders from different regions within the basal ganglia. Then, we used transneuronal transport of neurotropic viruses to define the targets of basal ganglia output from these behaviorally-characterized sites. The results of this approach have led to a number of striking conclusions about structure-function relationships within the basal ganglia. First, basal ganglia output is directed at multiple ‘motor’ and ‘non-motor’ areas of cerebral cortex. Second, the input-output organization of basal ganglia connections with the cerebral cortex is highly topographic. The topography within the basal ganglia predicts a topography of motor and nonmotor dysfunction. Third, in the course of these experiments we made the surprising discovery that the basal ganglia and cerebellum are interconnected and thus, communicate with one another. These interconnections may provide a framework for understanding cerebellar contributions to two prototypical basal ganglia disorders, Parkinson's disease and dystonia. Finally, transneuronal transport revealed that the ventral striatum is the origin of a major ‘open loop’ pathway to the cerebral cortex. This pathway could provide the neural substrate for some of the paradoxical motor abilities that patients with basal ganglia disorders display under special circumstances. Overall, our studies demonstrate how basic science research in non-human primates and a systems level approach can provide a framework for understanding the pathophysiology of a number of complex neurological and neuropsychiatric disorders.

Title: Task Representations, Why They Matter, and How We Learn Them

Abstract: In recent years, ideas from the computational field of reinforcement learning (RL) have revolutionized the study of learning in the brain, famously providing new, precise theories about the effects of dopamine on learning in the basal ganglia. However, the first ingredient in any RL algorithm is a representation of the task as a sequence of states. Where do these state representations come from? In this talk I will demonstrate using behavioral experiments, that animals and humans learn the structure of a task, thus forming a state space through experience. I will also present some results regarding the algorithms that they may use for such learning, and their neural implementation.
