Question

How does ‘phantom pain’ work? Is it due to your nerves or something in your brain? Why/how do amputees still feel the limb after it is gone?

In: Biology

Answer 1

Phantom limb: the neural pathways are still in the brain and spinal column and fire sometimes, causing it to feel like the limb is still there.
Phantom pain: when the brain and spinal column are confused about why the limb isn’t there anymore, the easiest way for them to cope with it is to trigger the pain response because it’s the easiest sensation to make.
