Detailed explanation-1: -Somatosensory cortex damage can result in numbness or tingling/prickling sensations (paresthesia) in certain parts of the body, depending on where the damage occurred. Since the face and hands have the most receptors and take up the largest area of the cortex, they are most vulnerable to numbness and/or tingling.
Detailed explanation-2: -Damage to the somatosensory cortex can produce numbness or sometimes paraesthesia, which is a tingling sensation in certain parts of the body. Numbness can result due to damage in the cortex which then affects the receptors on the body for certain areas.
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: -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.
