Document Summary
Analysis of visual information: role of the striate cortex. The striate cortex performs additional processing of the light information encoded by the retinal ganglion cells and transmits this information to the visual association areas. The striate cortex consists of six principal layers (and several sublayers), arranged in bands parallel to the surface. These layers contain the nuclei of cell bodies and dendritic trees that show up as light or dark in sections of tissue that have been dyed. The pioneering studies of hubel and wiesel began a revolution in the physiology of visual perception. Most neurons in the striate cortex are sensitive to orientation, meaning that the cell will only respond to a line or edge when it is in a particular orientation, be it vertical, horizontal, or in between. In addition, they responded equally well to white lines against black backgrounds and vice versa.
