The superior temporal gyrus is one of three (sometimes two) gyri in the temporal lobe of the human brain.
Additional recommended knowledge
A gyrus (plural gyri) is a bump or ridge on the surface of the brain.
The superior temporal gyrus is bounded by:
- the lateral sulcus above;
- the superior temporal sulcus (not always present or visible) below;
- an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly.
The superior temporal gyrus contains several important structures of the brain, including:
