Profile
Research expertise
Becket Ebitz is the PI of the noiseLab in the Departement de neurosciences. The lab is interested in how our internal states (our goals, beliefs, expectations, and even arousal) shape how we perceive and interact with the world. Our work combines (1) behavioral experiments, (2) direct, intracranial recordings from large populations of neurons, and (3) powerful causal perturbations. We use a variety of sophisticated computational methods to make sense out of neural activity and behavior. Although we are a neuroscience lab, we enthusiastically incorporate tools and insight from disciplines like artificial intelligence, economics, robotics, and ethology.
