In this double-bill webinar Tahl Holtzman (Founder of Cambridge NeuroTech) offers a general introduction to using our silicon neural probes in a variety of experimental settings encompassing anaesthetised, head-fixed and freely-behaving studies. Surgical approaches for chronic implantation are also covered. Nelson Totah (University of Helsinki) describes how he has applied chronically implanted probes to boost his single unit data yields in head-fixed behaving rats working on a GO / NO-GO task).
