The National Institute of Neurological Disorders and Stroke (NINDS) is considering to support the development and delivery of a complete recording system that is safe, efficient, and reliable for chronic implant applications, as demonstrated and validated by both in vitro and long-term in vivo testing. In past research and development, multiple microelectrode recording sites have been fabricated on shanks as small as 60 microns wide and 15 microns thick.
