Welcome to the “Roberto Vieira” Laboratory of Sensory Physiology. The focus of our study is the sensory mechanisms that lead to human perception. Through experimental and theoretical methods, ranging from psychophysical procedures and electrophysiological recordings to mathematical and computational modeling, we investigate sensory processes underlying visual perception, nociception and the dynamics of attentional allocation.


Marcus Vinícius Chrysóstomo Baldo, M.D., Ph.D.

I received an M.D. degree from the University of São Paulo School of Medicine (1985) and a bachelor's degree in physics from the Physics Institute, University of São Paulo (1989). An interest in neuroscience led to a Ph.D. in neurophysiology from the Department of Physiology and Biophysics, Institute of Biomedical Sciences, University of São Paulo (1990), followed by a post-doctoral training in visual psychophysics, University of California at Berkeley (1993-1995). As a post-doc at Stan Klein’s lab, in Berkeley, I began a line of investigation on the flash-lag effect, which evolved into a broader research program that includes temporal order judgment, time perception, spatiotemporal deployment of visual attention, interaction between action and perception, and nociception as well. I’ve been teaching physiology since 1988 at the same Department, now as an Associate Professor. I served on the Board of Directors, Brazilian Society for Neuroscience (SBNeC) as both Treasurer (2005-2008) and President (2008-2011).
