(1) Multi-target chronic recording and optogenetics in head-fixed marmosets & (2) Behavioural training of marmosets and electrophysiological recording from the cerebellum

Hear from leading-lights within the behaving marmoset field: Patrick Jendritza (Ernst Strungman Institute) describes his multi-target chronic probe implants across the visual cortices, encompassing 196-channel recording of single units with optogenetics for > 1 year in each animal. Reza Shadmehr and Paul Hage (Johns Hopkins University) describe their innovative approach for daily acute probe penetration spanning many months in head-fixed behaving marmoset to record cerebellar Purkinje cells; dura-repair techniques are also discussed.
