What transmits pain triggering signals to central nervous system?
The Role of the Spinal Cord in Pain Response Your spinal cord is a complex array of bundles of nerves, transmitting all kinds of signals to and from the brain at any given time. It is a lot like a freeway for sensory and motor impulses.

Is it possible to turn off pain receptors?
Scientists have discovered a new pain center in the brain that they may be able to ‘turn off’ to relieve agony for chronic nerve sensitivity. Nerve pain is one of the most difficult types of constant discomfort to treat because most painkillers do not target the correct receptors for it.
