35
Q

What is the Gate Control Theory of Pain?

A

Melzack and Wall’s Theory. It states that our experience of pain is not directly related to activation of pain receptors. Instead, neural gates in the spinal cored mediate the signal. Either the gates allow the pain signals to make it to the brain or not. Various physical and psychological variables control the gates.

36
Q

What is the Centralization of Pain Theory?

A

This theory posits that pain is affected by memory of previous pain. If you have a history of being exposed to frequent pain, you are more likely to experience plain. When considering the neuroplasticity of our brain, it can change in response to frequent pain signals so that it response more quickly to new pain signals with a lower threshold.
