Occipital lobe is one of the most important lobe of the four lobes of the cerebral cortex in the mammals brain.Occipital lobe is the visual processing unit of the mammalian brain containing most of the anatomical area of the visual cortex. The primary visual cortex is Brodmann area 17. The main function of visual cortex is processing of visual information.Visual nerves are running straight from the eye to primary visual cortex to the Visual association cortex. Cortical visual impairment is the reduced visual response because of a neurological problem affecting the brain's visual part.
