Pain is not a direct 1:1 signal from injury to brain; it is modulated. Competition:
These smaller fibers carry noxious stimuli. When their signals outweigh the input from touch fibers, the gate "opens," and pain is perceived. DDSC 018: Advanced Computational Modeling of Pain pain gate ddsc 018
The "pain gate" refers to a mechanism within the dorsal horn of the spinal cord that can either facilitate or inhibit pain signals traveling from peripheral nerves to the brain. Proposed by Ronald Melzack and Patrick Wall in 1965, the Gate Control Theory suggests that non-painful input (touch, vibration, pressure) can close the "gate" to painful input, preventing the brain from perceiving pain.
