The Spinal Reflex
Captions available
The idea
A spinal reflex is a response organized in the spinal cord that occurs before the signal reaches the brain.
In practice
A hand pulls back from a hot surface, and the pain is felt after the hand has already moved.
Where people slip
The brain is informed, not consulted. That order is the reason the reflex is fast enough to be useful.
