Question

as scientists continue to investigate phantom pain, they will better understand the mechanisms behind it and will be better able to come up with possible treatments. remember the previous description of phantom pain: phantom pain is pain that feels as if it is coming from a body part that has been removed. what else do scientists know about phantom pain? select all that apply. phantom pain can sometimes be stopped with treatments that reverse changes in the somatosensory cortex. phantom pain most likely occurs when the nervous system creates the sensation of pain in a body part that has been amputated. phantom pain can sometimes be treated with anesthetics that block atypical signals from severed nerves. phantom pain treatments work the same way for all patients.

Explanation:

• Phantom pain arises when the nervous system generates pain signals for an amputated body part, so this statement is correct.
• Treatments targeting somatosensory cortex changes can alleviate phantom pain, making this statement valid.
• Anesthetics blocking abnormal signals from severed nerves are a known treatment approach, so this is correct.
• Treatments do not work uniformly for all patients, as individual neurological differences exist, so this statement is incorrect.

Answer:

• Phantom pain most likely occurs when the nervous system creates the sensation of pain in a body part that has been amputated.
• Phantom pain can sometimes be stopped with treatments that reverse changes in the somatosensory cortex.
• Phantom pain can sometimes be treated with anesthetics that block atypical signals from severed nerves.
