Within the pain pathway there are 3 orders of neurones that carry action potentials signalling pain: First-order neurones - These are pseudounipolar neurones which have cells bodies within the dorsal root ganglion. The modulation of pain by electrical brain stimulation results from the activation of descending inhibitory fibers, which modulate (block) the input and output of laminae I, II, V and VII neurons. 2. The major site of modulation is dorsal horn of spinal cord. 2 Department of . The hypothalamic neuropeptide, oxytocin (Oxt), has been the focus of research for decades due to its effects on body physiology, neural circuits, and various behaviors. "Response modulation refers to directly influencing experimental, behavioral, or physiological components of the emotion response after the emotion is well developed." James Gross It is the physiological action tendency that contributes to such a great amount of our impulsivity especially when it is a highly reinforced habit of acting. This analgesic effect arises from activation of descending pain-modulating pathways that project, via the medulla, to neurons in the dorsal horn that control the ascending information in the nociceptive system.
