Gate Control Theory
Gate control theory explains that the spinal cord has a “gate” which may or may not allow pain signals to travel and reach the brain. This theory was proposed by Ronald Melzack and Patrick Wall in the 1960s. For instance, you would most likely be more sensitive to pain if you feel scared as compared to when you are in a relaxed state. Moreover, the gating system is said to be manifested when pain is lessened by massage, acupuncture, and meditation; as these techniques inhibit pain signals.
