The study sheds light on how the mechanisms of pain are altered after infant injury in a region of the brain called the periaqueductal gray, which is involved in the perception of pain.
These receptors are found in various central nervous system areas that are involved in pain perception and modulation, such as the periaqueductal grey, the thalamus, and the spinal cord dorsal horn [28].
Western medicine hypothesises that signals from stimulation of peripheral nerve fibres (possibly through acupuncture points) can influence hypothalamic functions via the dorsal periaqueductal grey fibres, and thereby influence the respiratory centre in the medulla, modifying respiration (Takeshige et al 1993).
