Detailed explanation-1: -Stimulating the left primary motor cortex would cause the right side of the body to move. The messages for movement and sensation cross to the other side of the brain and cause the opposite limb to move or feel a sensation.
Detailed explanation-2: -What is motor cortex stimulation? Motor cortex stimulation is a type of neuromodulation, which is a surgical procedure that implants electrodes in the body to change how the nervous system works. Motor cortex stimulation involves placing the electrodes on the surface of the brain to control pain signals.
Detailed explanation-3: -The primary motor cortex on the left side of the brain controls movement of the right side of the body, and vice-versa, the right motor cortex controls movement of the left side of the body.
Detailed explanation-4: -The right hemisphere controls the left side of the body, and the left hemisphere controls the right side.
Detailed explanation-5: -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.
