The patient is awake many times during brain surgery. in an operation to remove a brain tumor, dr. judson accidentally poked a certain area of the cerebrum, whereupon the patient said, "why is my arm being tickled?" what area was poked?
The answer is the Primary somatosensory area. A conspicuous structure in the parietal lobe of the human cerebrum that is the area of the essential somatosensory cortex, the fundamental tangible responsive range for the feeling of touch. The precentral gyrus lies before the postcentral gyrus and is the site of the essential engine cortex.
