Problem 15

Background and context

The outermost component of the brain refers to a thick piece of nervous system tissue known as the cerebral cortex that is encased in valleys known as sulci and hills known as gyri. The cortex is composed of two hemispheres, namely, the left and right hemispheres, which are distinguished by a large sulcus. The human cerebral cortex includes the parietal, frontal, occipital, and temporal lobes.
