Detailed explanation-1: -The correct answer is C. (Somatosensory cortex). Somatosensory cortex is located in the parietal lobe and processes touch and movement. When a part of somatosensory cortex is stimulated, we feel sensation in the body that this area is devoted to.
Detailed explanation-2: -Direct stimulation of somatosensory cortex evokes sensory perceptions, and is thus a promising option for closing the loop. Before this can be implemented in humans it is necessary to evaluate how changes in stimulus parameters are perceived and the extent to which they can be discriminated.
Detailed explanation-3: -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-4: -Answer-d. (d) Motor cortex is crucial for movement and bodily functions thereby stimulation of this part of the brain will cause movement of the lips and mouth.
Detailed explanation-5: -The somatosensory cortex is a region of the brain which is responsible for receiving and processing sensory information from across the body, such as touch, temperature, and pain.
