Auditory+Association+Areas

Location
The auditory area although originating in the depths of the superior temporal lobe extends in a continuous belt-like fashion posteriorly from primary and association (e.g. Wernicke's) area toward the inferior parietal lobule, and via the arcuate fasciculus onward toward Broca's area.

This massive rope of interconnections forms an Axis such that Wernickes Area, the inferior parietal lobule, and Broca's area.
 * Left Hemisphere**

These areas often become activated in parallel or simultaneously during language tasks, and together, are able to mediate the perception and expression of most forms of language and speech.

The rope-like arcuate and inferior and superior fasciculi are bidirectional fiber pathways, however, that run not only from Wernickes through to Broca's area but extends inferiorly deep into the temporal lobe where contact is established with the amygdala. Hence, via these connections auditory input comes to be assigned emotional-motivational significance, whereas verbal output becomes emotionally-melodically colored. Within the right hemisphere, these interconnections which include the amygdala appear to be more extensively developed.
