What is phantom limb sensation and describe why the patient experiences these sensations?
What will be an ideal response
When a limb has been amputated, the patient still feels the sensations of itch, pressure, tingling or pain as if the limb is still there. It is believed that the cerebral cortex interprets impulses arising in the proximal portions of sensory neurons that previously carried impulses from the limb as coming from the non-existing limb. Another possible explanation is that the brain contains networks of neurons that generate sensations of body awareness.
