Sarah Theobald & . Nestor Matthews. Department of Psychology, Denison University, Granville OH 43023 USA. . . The human brain is constantly being presented with complex visual information from all locations. As the retina receives information from either the left or right visual field, or hemifield, the information is processed predominately in the contralateral hemisphere.
