Question

scientists have identified one part of the brain that can change after an amputation. this part of the brain is called the somatosensory (suh-mat-uh-sen-suh-ree) cortex. it receives signals about physical sensations from limbs and other body parts.
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.
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 before 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.

Explanation:

The correct adjusted statement aligns with the provided text about phantom pain and somatosensory cortex changes after amputation. The original incorrect statement says the foot sends signals to the cortex before amputation, but the text clarifies the foot stops sending signals after amputation, and the cortex's change causes phantom pain.

Answer:

After the person's foot is amputated, it stops sending signals to the somatosensory cortex. When this happens, the somatosensory cortex can change in a way that may cause phantom pain.
