In This Respect Influence Of The Central Nervous

In this respect influence of the central nervous system reflecting an external world and even more changeable world of feelings and thoughts, not only is not necessary, but also would be inappropriate, would disturb to that should be made under the, internal laws. So, for example, if at a rat to remove a cerebral cortex, and then reproductive function can be carried out: the fertilisation, normally proceeding childbirth and posterity feeding. It shows that the central level of regulation for reproductive function is . On the other hand, if a rat to subject to a strong emotional overstrain, for example by means of intensive sound signals there will be a deenergizing of reproductive function. Differently, the central nervous system can interfere during automatic realisation of reproductive function if there is a necessity to adapt organism activity to the requirements shown by an environment, but does not supervise this activity needlessly. Therefore in many respects functions automatically, without the control from outside the central nervous system, obeying own rhythm and the signals arriving from a body.

Clearly That The Unusual Way Of Change Of

Clearly that the unusual way of change of regulation at which the cybernetic principle peculiar to all control systems, would be transformed to a dynamo-cybernetic, corresponding to the law of a deviation of a homeostasis was necessary. The given principle also underlies organism development (as we it saw on an example of maintenance of the mechanism of puberty). Thus, in are realised simultaneously and the law of a constancy of the internal environment, and the law of a deviation of a homeostasis. But there is one more property (as parts of nervous system) which provides performance of the law of a deviation of a homeostasis. Each nervous cage is tiny gland: it makes substances which basically differ nothing from typical hormones. With reference to nervous system these substances are designated as intermediaries, or transmitters - . The matter is that nervous cages, strictly speaking, do not form a continuous network on which the electric impulse-signal would move. The wires-shoots located close to a membrane of the next nervous cage depart from a body of each nervous cage.
