What is the primary visual cortex also known as?

• A. V3
• B. V1 or Striate cortex.
• C. V2
• D. Occipital lobe

Answer: (B)

The main idea here is that the first cortical stage that handles visual input is the primary visual cortex. This area, located in the occipital lobe along the calcarine sulcus, is classically called V1. It’s also known as the striate cortex because of its striped appearance in histology, produced by the dense myelinated fiber layers that feed into and out of this region. V1 is the initial cortical recipient of signals from the lateral geniculate nucleus of the thalamus and begins processing basic features like edges and orientations with a retinotopic map, before information moves on to the other visual areas (like V2 and V3) or other parts of the brain. The broader occipital lobe contains multiple visual areas, but the specific primary processing hub is V1, the striate cortex.
