Document Summary
Primary motor cortex (pmc) generally responsible for executing physical movements (lifting arm, leg etc. ) Homunculus how much space in pmc dedicated to different regions. Primary somatosensory cortex receive sensory information from skin etc. Contralaterlization touch on right side of body, the left side of brain will detect that touch. see image.
