The inferior portion of the occipital lobe in the visual cortex is known as the __________ gyrus.

• A. Lingual gyrus
• B. Cuneus gyrus
• C. Fusiform gyrus
• D. Precentral gyrus

Answer: (A)

The inferior surface of the occipital lobe that forms part of the visual cortex is the lingual gyrus. It sits below the calcarine sulcus on the inferior bank, making it the lower portion of the occipital visual cortex. The calcarine fissure splits the primary visual cortex, with the cuneus on the superior bank and the lingual gyrus on the inferior bank. The other options refer to regions outside this area: the cuneus gyrus is the upper counterpart on the superior surface, the fusiform gyrus lies in the inferior temporal lobe and is key for high-level object recognition, and the precentral gyrus is the primary motor cortex in the frontal lobe.
