Noceceptive system: features of physiological bases of functioning

This article is devoted to the features of the physiological functioning of the nociceptive system. Nociception is a neurophysiological term that describes the totality of the perception, conduct, and processing of signals about processes or effects. Accordingly, the system itself, which implements the translation of such signals, is called nociceptive. The concept of pain reflects a kind of subjective experience accompanying nociception. In addition, there are reactions to nociceptive irritation in the depressed mind. This article reflects the hypotheses that form the concept of a nociceptive system and the physiological mechanisms of perception, analysis and response to nociceptive information. Over the past decade, there has been tremendous progress in the study of the molecular features of phenomena and processes. Multicomponent reactions initiated by the reception of pain, develop according to certain algorithms, referring to the parameters of nociceptive signals, where the study of molecular markers is particularly promising. In the body there is also a specialized response to nociceptive information, which is called the antinociceptive system. The results of many years of research have revealed correlation parallels and significantly significant differences in the neurophysiological and neurochemical mechanisms of pain in a given pathological condition.
