Active neurons are a vital part of a functioning brain and an essential component of in vitro neurological models. In this webinar, Dr. Cedric Bardy talks about why and how he invented BrainPhys™, a new neuronal basal medium that better supports neuronal function in vitro, described in C Bardy et al. Proc Natl Acad Sci USA, 2015. Dr. Bardy describes how BrainPhys™ increases the physiological relevance of primary and hPSC-derived neuronal cultures in vitro.
