Begin by understanding the basic anatomy of the brain. The brain is divided into two main parts: the left and right cerebral hemispheres.
Identify the structures that separate or define different regions of the brain. These include various sulci (grooves) and fissures (deeper grooves).
The central sulcus is a groove that separates the frontal lobe from the parietal lobe, not the hemispheres.
The lateral fissure, also known as the Sylvian fissure, separates the temporal lobe from the frontal and parietal lobes, but does not divide the hemispheres.
The longitudinal fissure is the deep groove that runs along the midline of the brain, effectively dividing the brain into the left and right cerebral hemispheres.
