INI-CET 2017 — Anatomy

Q: The marked area in the image given below is associated with which part of brain cortex?

Striate cortex. ***Striate cortex*** - The image points to the **calcarine sulcus**, a prominent landmark on the medial surface of the occipital lobe. - The **striate cortex**, also known as the primary visual cortex (V1), is located along the banks of the calcarine sulcus. *Hippocampus* - The hippocampus is a structure located in the **medial temporal lobe**, involved in memory formation. - It would be found deeper within the temporal lobe, not on the medial surface of the occipital lobe as indicated. *Dentate nucleus* - The dentate nucleus is a **deep cerebellar nucleus**, located within the cerebellum. - The arrow points to an area of the cerebral cortex, not the cerebellum. *Orbital cortex* - The orbital cortex (or orbitofrontal cortex) is located in the **ventral-anterior part of the frontal lobes**. - It is involved in decision-making and reward, and its location is far removed from the area indicated by the arrow, which is in the posterior part of the brain. *Entorhinal cortex* - The entorhinal cortex is located in the **medial temporal lobe**, adjacent to the hippocampus. - It serves as a major input/output structure for the hippocampal formation and is not located on the medial occipital cortex where the calcarine sulcus is found.
