Final answer:
The primary auditory cortex is located in the superior temporal gyrus, which is a key area in the temporal lobe for processing auditory information and is identified as Brodmann's area 22. The correct option is A.
Step-by-step explanation:
The primary auditory cortex is located in the superior temporal gyrus. This area is responsible for processing auditory information and is designated as Brodmann's area 22. It is a part of the temporal lobe of the cerebral cortex, which also includes important functions associated with hearing, memory, and speech.
The pathway for auditory processing involves the inferior colliculus in the midbrain, which sends axons to the thalamus; specifically, the medial geniculate nucleus of the thalamus, which then relays auditory information to the auditory cortex in the temporal lobe.
