Auditory cortex

The auditory cortex receives input from the medial geniculate nucleus. It's functionally asymmetrical. It consists of these parts:

Primary auditory cortex (A1)
Located within Heschl's gyrus. Receives input from the ventral path of the visual pathway. Is organized in a tonotopical map which is maintained through the auditory pathway.

Secondary auditory cortex (A2)
Located next to Heschl's gyrus in the temporal lobe. Receives inout from the dorsal path.

Wernicke's area
Left hemisphere: Speech zone. Contains sound images of words, which is used to comprehend words. Connected to Broca's area through the Arcuate fasciculus.

Right hemisphere: Analyses music.
