Abstract: Evoked responses in the mouse primary visual cortex are modulated by experiential history and temporal context. Various groups have proposed that this modulation demonstrates predictive coding, though there is an active debate how about well the evidence supports this interpretation. In this talk I will discuss what V1 tells us about how cortical circuits learn to anticipate expected events, describe the role of cholinergic signaling in coding temporal relationships, and argue that oddball driven deviant responses support a predictive coding model. Finally, I’ll discuss the limitations of a V1-centric approach and explain why I think the best way to understand how neural time is linked to perception and predictive action requires teaching mice how to dance.

About the Speaker
Jeff Gavornik
at Boston University
Jeff grew up on and around US Air Force bases and graduated with a History major from Rice University then worked for several years for Boeing on the International Space Station program at the Johnson Space Center in Houston. He completed a Master of Electrical Engineering degree at Rice before earning a Ph.D. in the ECE department at the University of Texas at Austin based on his work in computational neuroscience. He performed experimental postdoctoral research in the HHMI at MIT before starting his lab in the Biology Department at Boston University. Jeff is associated with the Center for Systems Neuroscience, the Center for Memory and Brain, the Department of Biomedical Engineering, CRESCENT, the Neurophotonics Center, the Graduate and Undergraduate programs in Neuroscience, and probably other things as well. As far as we can tell, he invented "Austin Chili".
