TED-Ed: The fascinating science of phantom limbs - Joshua W. Pate

The video explores phantom limb sensations, which occur when individuals feel sensations in a limb that is no longer present. It explains that these sensations are due to a brain map of the body, which remains even after amputation. The video delves into the neural pathways involved and how changes in these pathways can lead to phantom pain. It also discusses the role of the somatosensory cortex in processing these sensations and how cortical representation can change. Treatments like mirror box therapy and prosthetics are highlighted, along with ongoing research to better understand phantom limbs and their implications for brain function.

How does the brain's cortical representation of body parts change in response to injury or amputation?

What are some potential future treatments for phantom limb sensations being researched?

Discuss the implications of phantom limb sensations for our understanding of the brain's mapping of the body.
