A New Network Architecture for Supervised Learning in the Cerebellum 

Javier F Medina, Baylor College of Medicine

The cerebellum is often described as a neural machine for supervised learning. Its network architecture consists of anatomically segregated learning modules, which are thought to be specialized for distinct functions defined by the error-related information received via the climbing fiber input, and by the few individual muscles each module is able to control. My talk will present our recent work on mouse eyeblink conditioning, focusing on two unpublished experiments that challenge this classic view about the organization of the cerebellum. First, I will describe a new recurrent circuit that allows some Purkinje cells in the cerebellar cortex to learn in the absence of error-related information in their climbing fiber input. Second, I will show that the output of a single cerebellar module can be used to control a complex motor synergy that requires coordination of multiple muscles. Altogether, the results suggest a new organizational framework for understanding what the cerebellum learns, and how.

CTN Research Day Sept 27 15:00-17:30 DWE 3516

The Centre for Theoretical Neuroscience will be hosting its first Research Day. This will be a chance to start the new academic year by getting re-acquainted with each other and the diversity of research conducted by CTN core and affiliate faculty. The format will be to have a number of CTN faculty share short overviews of their lab's and projects (15:00-16:00) and then, following a short coffee break (16:00-16:30), hear from a dozen current graduate students and post-docs giving short three minute talks on an aspect of their current research (16:30-17:30).
