can anybody find pain theories given by melzack & walls?

Question

theories and associated pathway also..

Answer 1

no, but can u give me points

Answer 2

"Neurophysiological theorizing on pain once started with the straightforward assumption that pain is nociception: the perception of tissue damage. At first, neurophysiologists postulated that there are specific receptors for such damage, and that stimulation of those receptors induce nerve signals which go to the brain. In the brain those signals are decoded and the information they contain evoke the sensation of pain and the knowledge concerning site and kind of tissue damage. Melzack (1986: 2) described this view as the “traditional specificity theory of pain”. The subsequent history of the field shows a number of important revisions of those initial ideas (see reviews by Fields 1987, and Van Cranenburgh 1987). One soon discovered that there are different types of nerve fibres, each with its own characteristics. Signals from these different fibres were then found to interact and to be integrated at different levels. The (ventral horn of the) spinal cord is a first important junction. What happens there is the subject of Melzack and Walls much debated Gate Control Theory (see Wall 1978; Melzack 1986). But convergence of nerve fibres and integration of nerve signals goes on in various steps higher on. The specificity once central to neurophysiological research on pain, was pushed back to the periphery: sensation specificity (the direct link between the tissue damage and what one feels) was replaced by receptor specificity (a link between tissue damage and the firing pattern of ‘pain’ fibres close to that damage)."
