Visual Computation

We tend to trust our eyes, believing them to be reliable purveyors of information about our visual environment. In truth, however, the signals they produce from moment to moment are noisy and incomplete. How do we 'decide' what we see based on such limited and uncertain information? What brain mechanisms underlie this ability? What neural computations allow us to improve the reliability of sensory information and make better visual decisions? Our lab uses a combination of neuroimaging (fMRI), computational modeling and visual psychophysics to address these and other questions regarding the neural basis of human vision.
