The members of the Cerebellar Physiology team are working together to unravel the role of the cerebellum in sensorimotor integration, from synaptic to systems levels. We use our strong interest in neurophysiology and development of optical tools for neuroscience to explore the biophysics of synaptic transmission and how it is integrated by the cerebellar cortex microcircuit during sensorimotor integration in awake behaving animals. Our team combines complementary technical expertise in cerebellar physiology ranging from single synapse electrophysiology up to imaging populations of neurons in mice performing cerebellar-dependent motor tasks.
