Which term is another name for the primary visual cortex?

• A. V2
• B. V3
• C. V4
• D. Striate Cortex

Answer: (D)

The primary visual cortex is the first cortical stage that processes visual information, receiving direct input from the lateral geniculate nucleus and mapping the visual field across the surface. It is called Striate Cortex because histology reveals a distinct stripe of myelinated fibers in layer IV, the stripe of Gennari, which gives it a striped appearance under the microscope. This striped, highly myelinated band is what led to the traditional name Striate Cortex, and it corresponds to the region often labeled V1 or area 17 in Brodmann’s map. The other areas listed are higher-order visual regions that follow V1 and handle more complex processing, so they aren’t the primary visual cortex. Therefore, Striate Cortex is the term that best names the primary visual cortex.
