Question 6

Gate control theory

Answer 6

The spinal cord contains a neurological ‘gate’ that blocks pain signals or allows them to pass to the brain.
The ‘gate’ is opened by the activity of pain signals travelling up small nerve fibers.
The ‘gate’ is closed by activity in larger fibers, or by information coming from the brain. The brain can close the ‘gate’ and flood the body with endorphins to reduce or even completely eradicate pain sensation for a short duration.
