Question

Chris also lost his left thumb, but he doesn’t have any phantom sensation when touching his forehead, like Juliette does. If Chris were to undergo an MRI and have his forehead stroked with a brush, which somatosensory regions would you expect to be active:
A) Only the forehead region
B) The forehead and the thumb region
C) Only the thumb region
D) None of the above

Answer 1

Answer:

The answer is B the forehead and the thumb region

Explanation:

when taking the magnetic resonance we will notice that there is activation of the somatosensory region of both the forehead and the thumb at the brain level, although Chris has no phantom sensation, in his brain his somatosensory point is present.
