**EXCITEMENT, in cybernetics** — process of transition of dynamic system of a condition of rest in a nek-swarm excited state under the influence of the revolting influences. At the same time the revolting influence is understood as the external or internal energy transferring system from one state to another.

Methods of the theory of management are applied to studying of patterns of V. of various systems in cybernetics. Much attention, in particular, is paid to development of mathematical models B. biol, systems and their elements — neurons and nerve fibrils. Certain results are received also in the field of mathematical modeling of mechanisms B. of other living tissues.

These models are used as for studying of processes of V. in biol, systems, and for creation of the corresponding technical systems, such as, e.g., systems bioelectric management (see).
