We study mid- and high-level visual processing, specifically links between visual perception, eye movements and neural circuits. We use neurophysiological, psychophysical and computational approaches, combined to improve our understanding of the cortical substrates of natural visually guided behavior (‘natural vision’). Our neurophysiological experiments make extensive use of linear and nonlinear systems identification techniques to characterize single neuron selectivity in striate and extrastriate visual cortex.

In humans, we have developed novel gaze-contingent psychophysical methods to investigate the reference frame or coordinate system used to encoded and sustain spatial attention across saccadic eye movements. This work lies at the intersection of visual attention, working-memory and oculomotor behavior and is intended to explore how all three of these subsystems interact during naturalistic behaviors that depend on eye movements.

James Mazer

Dr. Mazer recieved a PhD in Biology from Caltech in 1995, where he studied the neural substrates of sound localization in barn owls in Dr. Masakazu Konishi's laboratory. He completed postdoctoral training at MIT with Dr. Peter Schiller (1996-1999) and UC Berkeley with Dr. Jack Gallant (1999-2004) where he studied striate and extstriate visual cortex and top-down attentional modulation of feature selectivity during natural vision. He joined the Department of Neurobiology at the Yale School of Medicine in 2004, where he was a professor of Neurobiology and Psychology until 2016. In 2016 he moved to Bozeman, Montana to join the Department of Cell Biology and Neuroscience at Montana State University.
