We are part of the Department of Neuroscience at the University of California at Berkeley. Our research focuses on understanding the functional organization of the frontal cortex at the single neuron level. Our methods use sophisticated behavioral paradigms, multichannel recording and computational analysis of neuronal data. We aim to understand the neuronal mechanisms underlying a number of high-level cognitive and behavioral processes, including decision-making, learning, and working memory. The goal of our research is to guide the development of the next generation of treatments for mental illness.

Another scrum at the Wallis lab posters at this year’s Society for Neuroscience meeting in Chicago.

April 2024

New paper in Nature Neuroscience via our collaboration with Steven Kennerley, which showed that neurons encode a distribution of prediction errors in anterior cingulate cortex, consistent with distributional reinforcement learning.

Alyssa Sanchez joins our lab as a Postdoctoral Fellow. Alyssa graduated from Martin Usrey’s lab at U.C. Davis where she studied the visual responses of the lateral geniculate nucleus. Welcome to the other end of the brain Alyssa!
