Video The Mind’s Eye

We live in a three-dimensional world, but each of our eyes only receives a two-dimensional image. How does our brain combine these images?

Research in the Rokers Vision Laboratory, in the Department of Psychology at UW–Madison, focuses on the neural mechanisms underlying visual perception, with an emphasis on motion and depth perception. Signals from the two eyes need to be combined in visual cortex in order to inform us of the position and movement of objects.

The study of motion and depth perception helps uncover the function and underlying architecture of the brain’s visual system and provides us with a model by which to understand visual processing in general. To do so we use complementary behavioral, neuroimaging and computational approaches.

Research at the Rokers Vision Laboratory improves the understanding and treatment of visual impairments with a cortical basis, such as amblyopia (lazy eye) and motion blindness, ultimately leading to the recovery of lost visual function.
