Answer: D. 22

Explanation: Area 22 is known as auditory association cortex. Wernicke’s area lies in the posterior part of area 22 (in the posterior third of the superior temporal gyrus).

Areas in temporal lobe:
1. Area 41 is the primary auditory cortex
2. Area 42 is the associative (secondary) auditory cortex
3. Together, these areas are referred to as Heschl’s gyrus.
4. Adjacent to Heschl’s gyrus lies the planum temporale. It is involved in language and music.
