I believe it is the temporal lobe.

Posterior portion of the superior temporal gyrus in the temporal lobe

Superior frontal gyrus, superior temporal gyrus, superior frontal sulcus, superior temporal sulcus

The superior temporal gyrus contains the primary auditory cortex, which is responsible for processing sounds. Specific sound frequencies map precisely onto the primary auditory cortex. This auditory (or tonotopic) map is similar to the homunculus map of the primary motor cortex. Some areas of the superior temporal gyrus are specialized for processing combinations of frequencies, and other areas are specialized for processing changes in amplitude or frequency. The superior temporal gyrus also includes the Wernicke's area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language. The superior temporal gyrus (STG) is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition.

prosopagnosia: inability to recognize faces

Any hook-shaped or curved part of a body process.

esp. the hippocampal gyrus in the temporal lobe of the brain.

Hope i helped :)
