Answer:

Primary visual cortex is a multilayered structure present in the occipital lobe (back of the head) and its main function is to perform initial processing of visual information about static and moving objects. There are specialized regions in the primary visual cortex that process different atttributes or features of an object like size, color, pattern, depth, texture etc.
Primary visual cortex consists of specialized cells (simple, complex and hypercomplex) that acts as feature detectors. Simple cells have an elogated receptive field and respond primarly to points of light, orientated edges, angle, position, gratings etc. Neurons present in the primary visual cortex selectively respond to edges oriented at each position in the visual field and turn into a particular edge orientation clusture (orientation columns). The cells in the orientation column have the same preferred orientation and respond preferentially to images of bars or edges.

Compare the auditory and visual projections from the sense organ to the cortex. How are they similar? How are they different? Include information about the sense organs and cranial nerves, the number of relays in the brain and where they are located, and where they terminate in the cortex. Do both systems have modularity? Explain.
