Question

Quizplus · Accepted Answer

The somatosensory cortex is responsible for processing tactile information such as touch, pressure, and temperature. Therefore, stimulation of this area is likely to result in a sensation on the skin, such as a tingling feeling. Swirls of color and bright flashes of light are more likely to be associated with stimulation of the visual cortex, while nothing at all would suggest that the probe is not successfully reaching or stimulating the cortex.
