Question

what might happen to the somatosensory cortex of a person who has a foot amputated? click the blue words to correct the following statements. before the person’s foot is amputated, it sends signals to the somatosensory cortex. but after the foot is amputated, the somatosensory cortex does not receive signals from the foot. when this happens, the somatosensory cortex can change in a way that may cause phantom pain. when a body part is amputated, it stops sending signals to the somatosensory cortex. when this happens, the somatosensory cortex itself can change. some scientists think that these changes in the somatosensory cortex create new types of signals in the brain. the scientists hypothesize that the brain interprets these signals as phantom pain in the body part that has been amputated.

Explanation:

The correct statements align with the provided text about phantom pain and somatosensory cortex changes after amputation. The text states that after amputation, the body part stops sending signals, the somatosensory cortex changes, these changes lead to new brain signals interpreted as phantom pain, and the cortex changes in a way that causes phantom pain (it no longer receives foot signals).

Answer:

• When a body part is amputated, it stops sending signals to the somatosensory cortex.
• When this happens, the somatosensory cortex itself can change.
• Some scientists think that these changes in the somatosensory cortex create new types of signals in the brain. The scientists hypothesize that the brain interprets these signals as phantom pain in the body part that has been amputated.
• But after the foot is amputated, the somatosensory cortex does not receive signals from the foot. When this happens, the somatosensory cortex can change in a way that may cause phantom pain.
