Afferentation
Afferentation (Latin afferens, afferentis - bringing) is a stream of nerve impulses that enter the central nervous system from intero- and exteroreceptors. Anokhin P. K., Soviet physiologist, academician of the USSR Academy of Medical Sciences (1898-1974), proposed the following terms used to designate the types of afferentation:
- Reverse afferentation - the principle of the body's functional systems, which consists in carrying out a constant assessment of a useful adaptive result by comparing its parameters with the parameters of the acceptor of the result of the action;
- Environment afferentation is a component of afferent synthesis, which is the effect on the body of all external factors that make up a specific situation, against the background of which adaptive activity takes place;
- Starting afferentation is a component of afferent synthesis that implements the already formed prestarting integration of excitations into a behavioral act; a conditioned stimulus belongs to the characteristic type of triggering afferentation.
