In this video, I cover the pathway visual information travels moving from the eye to the visual cortex and surrounding areas. First, I discuss the components of the eye that focus light on the retina. Then, I describe the anatomy of the retina along with the functions of the different cell types found there. Next, I cover the pathways that carry visual information from the retina to the primary visual cortex. Finally, I describe how the primary visual cortex recruits surrounding visual areas to further process visual information.
