The medullary reticular formation receives a major immediate projection through the spinal twine along with from branches of many of the spinal neurons that task into the thalamus (Kevetter and Willis, 1984; Mehler, 1962).
As we find out more about the transduction system, it may be possible to evaluate the focus of substances in locations of ongoing tissue hurt that activate or sensitize Main afferent nociceptors. This may give an estimate of the extent of stimulation of chemically sensitive nociceptors.
As a result, You will find there's variable relation among nociceptor enter and perceived pain depth. For this reason the method of recording Main afferent nociceptors may very well be made use of to substantiate the existence of the input, but it really couldn't be accustomed to show that pain was not current.
