What is phantom limb syndrome?

Phantom limb syndrome is characterized by the sensation that a limb, which has been amputated or is otherwise missing, still exists. Individuals experiencing this syndrome may report feelings of warmth, cold, or even pain in the area where the limb used to be or may have the sensation that the limb is still present but in a different position or configuration. This phenomenon underscores the complex relationship between the brain, body, and sensory perception, highlighting how the neural pathways and brain regions associated with the missing limb remain active long after its physical removal. Understanding this condition provides insight into the brain's role in body representation and sensory processing, as well as the psychological aspects of limb loss.
