Where is the auditory cortex?

The primary auditory cortex, i.e. where the auditory signal first reach the cortex, is located on the Heshl's gyrus, on the supratemporal plane (the upper part of the temporal lobe). The auditory information then spreads to secondary auditory cortices located around primary the primary auditory cortex. Then the auditory signal diffuses to associative areas located in the parietal and frontal lobes.
