Suppose you are a patient in one of Penfield's famous experiments involving stimulation of the somatosensory cortex. During the procedure, the brain stimulation causes you to feel a tingling in your right arm. If Penfield moves the probe a centimeter along the cortex and stimulates the brain there, which part of your body will most likely feel a tingle?

Question

The somatosensory cortex is organized somatotopically, meaning adjacent areas of the cortex correspond to adjacent parts of the body. Since the initial stimulation caused a sensation in the right arm, moving the probe slightly would likely affect an area close to the arm, such as the right elbow.
