Where is the somatosensory cortex located in the brain?
Quick Answer
The somatosensory cortex is in the parietal lobe, just behind the central sulcus on the postcentral gyrus. It processes touch, pain, temperature, and body position.
The Full Story
The primary somatosensory cortex is located on the postcentral gyrus of the parietal lobe, directly behind the central sulcus. It receives information from the body about touch, pressure, vibration, pain, temperature, and proprioception. Like the motor cortex, it contains a somatotopic map of the body called the sensory homunculus. This arrangement allows the brain to represent different body areas with varying levels of detail.
