Beyond retina to visual cortex, a review

Abstract-Retina and visual cortex system is an important regarding the light energy to retina ,information processing, the perception and cognition, and visual contrast, color, movement, depth. V1 (primary visual cortex) is the hallmark of early cortical computation in visual system. This is important to know that how V1 encodes images. The notion was first directed to the primary visual cortex by discovery of of the edge and line detector neurons by Hubel and Weisel in late 1950, from computing sciences to behavioral diseases, memory disorders all are engaged in this system.
