AP PSYCHOLOGY

Detailed explanation-1: -The primary somatosensory cortex is called S1. This area of the cerebral cortex receives sensory information from the somatic senses, plus proprioceptive senses and some visceral senses. It is located on the postcentral gyrus of the parietal lobe, as shown in Figure 4.3.

Detailed explanation-2: -Sensory Cortex: The area at the front of the parietal lobes that registers and processes body touch and movement sensations.

Detailed explanation-3: -The somatosensory cortex in the front part of the parietal lobe resides in two areas: the postcentral gyrus and the posterior paracentral lobule. It helps process and interpret touch sensations and helps discriminate between them.

Detailed explanation-4: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-5: -The primary somatosensory cortex is located in a ridge of cortex called the postcentral gyrus, which is found in the parietal lobe. It is situated just posterior to the central sulcus, a prominent fissure that runs down the side of the cerebral cortex.
