A gyrus (plural gyri) is a bump or ridge on the surface of the brain. The superior temporal gyrus is one of three (sometimes two) gyri in the temporal lobe of the human 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:
- Brodmann areas 41 and 42, marking the location of the primary auditory cortex, the cortical region responsible for the sensation of sound;
- Wernicke's area, Brodmann 22p, an important region for the processing of speech so that it can be understood as language.
