Study Notes
Gate Control Theory
- The neural structure in the spinal cord that can open and close to modulate the perception of pain is the "gate".
Melzack and Wall's Contribution
- In 1965, Melzack and Wall described the gate control theory.
Gate Closure
- When the gate is closed, the transmission of pain signals to the brain is blocked.
Gate Stimulation
- The gate is opened by stimulation of small, unmyelinated C-fibers and A-delta fibers, which transmit pain information.
- The gate is closed by stimulation of large, myelinated A-beta fibers, which transmit non-painful sensations.
Psychological Factors
- According to the gate control theory, psychological factors, such as anxiety, attention, and past experiences, can influence the perception of pain by modulating the opening and closing of the gate.
