, 2. Transmission - Is the conduction of pain impulses along the A-beta and C-fibers into

the dorsal horn of the spinal cord.

3. Perception - Is the conscious awareness of pain, which occurs primarily in the reticular

and limbic systems, and the cerebral cortex.

4. Modulation - Involves many different mechanisms that increase or decrease the

transmission of pain signals throughout the nervous system.Depending on the mechanism,

modulation can occur before, during, or after pain is perceived.

*The Gate Control Theory Of Pain.

Pain transmission is modulated by a balance of impulses conducted to the spinal cord, where

cells in the substantial gelatinosa function as a "gate" that regulates the nociceptive transmission

to higher centers in the CNS. Does not account for phantom pain.

Gate opens= Increased perception of pain (Large A fibers)

Gate closes= Decreased perception of pain (small C fibers)

*The Pattern Theory Of Pain

Describes the role of impulses, intensity, and the re-patterning of the CNS.Although this theory

evolved to provide an explanation for neuropathic pain, this theory does not account for all types

of pain experiences.




*The Specificity Theory of Pain

The intensity of pain is directly related to the amount of associated tissue pain.

Only accounts for acute pain.
