WebThe non-neural descending pathways are not included in this figure. We refer to the signals generated by the central nervous system (CNS), often in response to interoceptive input, to regulate the interoceptive processes as 'regulatory signals of interoception'. WebTo do this, it is important to understand what constitutes the total pain experience. It consists of: 1) signal transduction at the peripheral receptor site, 2) signal conduction along the peripheral nerve, 3) pain modulation at the level of the spinal cord, 4) pain perception at the supraspinal site, and 5) the associated sensations, emotional ...
