Measuring severity of spinal cord injuries

spinal cord injuryInjuries to the spinal cord partially or completely disrupt the neural pathways between the brain and the limbs. The consequences for the representation of the affected limbs in the brain can be drastic. Researchers have now measured how severely this representation is affected.

A strange sensation, but familiar to anyone who has ever been given local anaesthesia and watched while a doctor operated on their leg or arm: in that moment, your own body part seems foreign, as if it doesn’t belong to your body. One reason for this is that the brain still knows which position the limb occupied before the local anaesthetic took effect. As soon as it wears off, the spooky sensation disappears.
