The "Gate" is a mechanism in the dorsal horn of the spinal cord. It modulates sensory input before it is perceived as pain by the brain.

TENS machines are specifically designed to stimulate large nerve fibers to "shut the gate" on chronic pain signals. Potential Context for "DDSC 018"

Large nerve fibers (which carry touch or vibration signals) "close" the gate by activating inhibitory neurons, which blocks the pain signals from passing through. Applications of the "Pain Gate"
