Systems neuroscience aims to understand how brain cells and circuits are organized to produce behavior in living organisms. Julio Martinez-Trujillo, M.D., Ph.D., shares his research studying how neurons interact with one another and other cell types within a circuit during ex vivo and in vivo conditions. He also looks to the future and discusses how stem cell technologies can provide unique access to study human circuits and new insights into the nervous system.
