<prompt> Visual processing center is located in -Frontal lobeTemporal lobeParietal lobeOccipital lobe  <response>: Ans. is d i.e., Occipital lobe o The occipital lobe is the visual processing center of brain containing most of the anatomical region of visual cortexo Primary visual area is brodmann area 17 also called VI on medial side of occipital lobe in calcarine sulcus. It is also called as striate area or striate cortex because it can be identified by a large stripe of myelin, the stria of gennari.LobeArea Area No.LocationFunctionLesion1.
