Gate Control Theory proposes that the perception of pain is not solely the result of direct activation of pain fibers, but is modulated by a 'gate' mechanism in the spinal cord that can increase or decrease pain signals before they reach the brain. This theory suggests that psychological factors, such as attention and emotions, can influence the experience of pain by affecting the gate's opening and closing.

It involves both voluntary and involuntary mechanisms that can be influenced by various internal and external factors, such as motivation, interest, and stimuli salience.
