Question

Quizplus · Accepted Answer

Phantom sensations for a missing limb are most likely the result of increased sensitivity of the region of the sensory cortex that formerly registered sensations from the missing limb. Even though the limb is no longer present, the brain still receives signals from the nerves that originally carried information from the missing limb. Over time, these signals can lead to changes in the sensory cortex, causing it to become more sensitive and responsive to touch or movement. This can result in the experience of phantom sensations, such as tingling, numbness, or even pain, in the missing limb.
