Part of this exercise included watching two videos that illustrate Dr. Ramachandran’s work with phantom limb syndrome. Based on your experience reviewing the content of these videos, which of the following is TRUE?
His study of the brains of those with missing limbs has not helped a broader understanding of brain activity and function in those without amputations.
The region of the somatosensory cortex that had been devoted to input from the missing limb eventually ceases to function, and essentially becomes a “dead zone” of neurons from the prolonged lack of incoming signals.
He was able to provide neurological evidence that a person will experience sensation in a missing hand, via stimulation of parts of the face, because the parts of the somatosensory cortex that manage input from these parts of the body are in close proximity to each other, and share incoming information.
