The Human Vision and Eye Movement Laboratory studies higher cerebral visual and ocular motor function in people. We use three main methodologic approaches: normal human psychophysics, studies in neurologic populations, and MRI studies (fMRI and DTI), supplemented by collaborations with researchers using event-related potentials and MEG. Our study areas include two main themes:
Additional areas of study include the attentional processing in Balint's syndrome, scanpath generation in face and scene processing by controls, autistic subjects and patients with visual agnosia, and the neuroanatomy of motion processing in collaboration with Debbie Giaschi.
