12. Pain & the Gate Control Theory
Pain message from the body travels on two separate sets of nerve fibers
The fibers carrying pain messages contain pain gates, which are open when we experience pain.
The non-pain fibers can actually close the pain gates.
This is why rubbing the hurt area or icing it can partially block the sensations of pain.
The brain plays a huge part
Example: athletes may get hurt, but their level of focus & adrenal helps them block out the pain for awhile.

Compare & Contrast your own reactions to temperature, pressure and pain
List stimuli
Ex. Receiving a shot of novocaine
What is your reaction to the intensity of the discomfort?
