They are called sulci and they allow for a greater surface area of the cortex of the brain which is where the majority of the neurons reside.
it is the surronding of th brain
The brain. Sulci are the valleys, gyri are the hills when looking at the surface anatomy
Lateral Genicluate Nucleus
it is the brain stem
Central sulcus
The insular cortex (abbrev. insula) is a structure of the human brain. It lies deep to the brain's lateral surface, within the lateral sulcus which separates the temporal lobe and inferior parietal cortex.
Insula is the cerebal lobe deep within the lateral sulcus.

Fissures.
You have sulci ( singular is sulcus) and gyri ( singular is gyrus) in the surface of the brain. By this mechanism you have the surface area of the brain, vastly increased.
A sulcus is a depression or fissure in the surface of the brain.
The Sylvian fissures are deep grooves in the cortex of the brain. They allow the Thebrain to be folded so more brain tissue can fit into the brain case. The Sylvian fissure is the deepest and most discernible of all the brains fissures. It is the lateral groove that divides the lobes of the human brain, in effect dividing the top and bottom of the brain. At the front of the brain it separates the frontal lobe from the temporal lobe, whilst at the back of the brain it separates the temporal lobe from the parietal lobe.

The ears are lateral to the brain. The brain is more towards the center of the body, so it is medial to the ears.
