Detailed explanation-1: -The primary somatosensory cortex (S1) plays a critical role in processing afferent somatosensory input and contributes to the integration of sensory and motor signals necessary for skilled movement.
Detailed explanation-2: -What evidence suggests that the somatosensory cortex is essential for the conscious perception of touch? People are conscious of only those touch stimuli that produce sufficient arousal in the primary somatosensory cortex.
Detailed explanation-3: -The primary somatosensory cortex is responsible for processing somatic sensations. These sensations arise from receptors positioned throughout the body that are responsible for detecting touch, proprioception (i.e. the position of the body in space), nociception (i.e. pain), and temperature.
Detailed explanation-4: -The somatosensory cortex is an important part of the cerebral cortex in the brain that processes sensory information from the body. Neurons from different parts of the body that receive environmental stimuli all send their information to the somatosensory cortex.
