Abstract

Brain injury affecting occipital cortex can result in an area of cortical blindness affecting the corresponding region of visual field. The ability to respond to certain visual stimuli presented within this blind area in the absence of conscious awareness is known as Blindsight. Many aspects of visual processing have been investigated, including spatial vision, processing of color, emotional expression, and semantic processing. Neuroimaging evidence highlights the importance of several frontal brain regions, as well as processing in the intact hemisphere for conscious awareness of visual processing. © 2009 Elsevier Inc.
