Which lobe contains the primary auditory cortex?

• A. Parietal lobe
• B. Occipital lobe
• C. Frontal lobe
• D. Temporal lobe

Answer: (D)

Hearing is processed in the temporal lobe. The primary auditory cortex, A1, sits on the transverse temporal gyrus within the superior temporal gyrus (Heschl’s gyrus) of the temporal lobe. It receives input from the auditory pathways via the thalamus and handles basic sound features like pitch, loudness, and timing. The other lobes specialize in different functions—occipital for vision, parietal for somatosensory and spatial processing, and frontal for movement and higher cognition—so the temporal lobe is the correct location for the primary auditory cortex.
