Primary somatosensory cortex for face, trunk, and arms is in which lobe?

Explanation:
The primary somatosensory cortex, which processes touch and proprioceptive information from the body, sits in the parietal lobe. Specifically, it lies in the postcentral gyrus and contains a somatotopic map of the body—the sensory homunculus—where sensations from the face, trunk, and arms are represented. This is why those body areas are processed in the parietal region. The frontal lobe is mainly involved in movement and planning, the temporal lobe in hearing and memory, and the occipital lobe in vision, so they’re not where the primary somatosensory cortex resides.
