The primary auditory cortex is the region of the brain that is responsible for the processing of sounds or auditory information. Click on the next link to see the image of this area on the human brain.

The primary auditory cortex receives input from the ear and lower centers of the brain, and it also transmits signals back to these areas. For each tempo or sound frequency, there is a corresponding part of the basilar membrane in the inner ear which responds to the sound, and sends a signal to the auditory cortex.
