Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
One foundation of learned behavior is the ability to associate arbitrary combinations of stimuli and actions. After learning a sensorimotor association, the brain transforms previously meaningless stimulus information into a specific motor command, but it is unclear where this transformation occurs and how it develops across learning. We are investigating how the cortex-basal ganglia circuit is involved in this type of learning by recording widespread activity while mice perform simple sensorimotor tasks. Our findings are building towards a cascade of events during learning, where sensory responses are increased in the basal ganglia, funneled into behavioral relevance, and routed to motor regions of the cortex. Surprisingly, this cascade appears to be different for visual and auditory stimuli, suggesting possible specialized circuits depending on the modality.
