Our research uses techniques derived from the brain-machine interface literature, such as real-time decoding and closed-loop microstimulation, with the goal of developing novel treatments for neuropsychiatric disorders that involve impaired decision-making including addiction, obsessive-compulsive disorder, and schizophrenia. https://images.squarespace-cdn.com/content/v1/61c0cc299a4f8649c626a38d/f14cfe24-f0bf-4065-bd02-bdeedf123b96/fig+1+neuropixels+website.jpg Home - News Neuropixels recordings! We are now recording from multiple Neuropixels probes, and record several hundred neurons a day, or about half a terabyte of data. We are continuing to scale up. https://images.squarespace-cdn.com/content/v1/61c0cc299a4f8649c626a38d/3221cfbe-506c-4344-b4cf-0e5c2a4d3615/logo+website.jpg Home A new Department of Neuroscience! After five years of hard work, we finally have a new Department of Neuroscience. It is the first academic department at U.C. Berkeley in 30 years. https://images.squarespace-cdn.com/content/v1/61c0cc299a4f8649c626a38d/bff4bc6f-8afe-4088-a92d-ba11db2f2fb4/fig+6+phase+modulation+web.png Home - Recent publications Elston, T.W. and Wallis, J.D.
