Thus there is new more difficult mediated time communication. It is necessary to underline that a reinforcement for a conditioned reflex of the second order is the conditional irritant of the first order, instead of an unconditional irritant food as if both light and a sound to support with food there will be two separate conditioned reflexes of the first order.
At strong enough conditioned reflex of the second order it is possible to develop a conditioned reflex of the third order. The new irritant, for example, a touch to a skin is for this purpose used. In this case the touch is supported only with a conditional irritant of the second order sound, the sound raises the visual centre, and last – the food centre. There is even more difficult time communication. Reflexes of higher order 4, 5, 6 and etc.
are developed only at primacies and the person. Dynamic stereotype Separate conditioned reflexes in a certain situation can communicate among themselves in complexes.
If to carry out a number of conditioned reflexes in strictly certain order with approximately men clomid time intervals and all this complex of combinations repeatedly to repeat, in a brain the uniform system having specific sequence of reflex reactions will be generated, i.
isolated reflexes communicate in a uniform complex. Нейроны a brain, possessing the big functional mobility, nevertheless can keep with firmness system of responses to repeating conditional irritations. There is a dynamic stereotype which is expressed that on system of the various prearranged signals operating always one after another through certain time, the constant and strong system of responses is developed.
Further, if to apply only the first irritant all other reactions will develop in the answer. Dynamic stereotype – prominent feature of mental activity of the person. Many our skills, for example, ability to write, play musical instruments to dance and etc. in effect are automatic chains of impellent certificates. In the course of human life more difficult stereotypes of acts are usually developed also behaviour after awakening or before a dream, a mode of work, rest, a food.
There are rather steady forms of behaviour in a society, in mutual relations with other people, in an men clomid of current events and reactions to them. Such stereotypes are of great importance in human life as allow to carry out many kinds of activity with smaller pressure of nervous system.
The biological sense of dynamic stereotypes is reduced releasing корковые the men clomid from the decision of standard problems, to provide performance more difficult, demanding heuristic thinking. Braking of conditioned reflexes For maintenance of the adaptation and adequate behaviour are necessary not only ability to development of new conditioned reflexes and their long preservation, but also possibility
elimination of those conditioned-reflex reactions necessity in which is absent.
Disappearance of conditioned reflexes is provided clomid 150 braking processes. On I. Pavlovu, distinguish following forms коркового braking unconditional, conditional and other-wordly braking.
Unconditional braking This kind of braking of conditioned reflexes arises at once in reply to action of an extraneous irritant, i. is the congenital, unconditional form of braking. Unconditional braking can be external and other-wordly. External braking arises under the influence of the new irritant
the prepotent centre of excitation, forming a rough reflex. Biological value of external braking consists that, затормаживая current conditioned-reflex activity, it allows to switch an organism to definition of the importance and degree of danger of new influence.
The extraneous irritant, making braking impact of a pas a current of conditioned reflexes, is called as an external brake. At repeated repetition of an extraneous irritant the caused rough reflex gradually decreases, and then disappears and any more does not cause braking of conditioned clomid or serophene. Such external braking irritant is called as men clomid dying away brake.
If the men clomid irritant contains biologically important information it every time causes braking of conditioned reflexes. Such constant irritant is called as a constant brake. Biological value of external braking – maintenance of conditions for more important at present the rough reflex caused by an emergency irritant, and creation of conditions for its urgent estimation. Conditional braking internal It arises, if the conditional irritant ceases to be supported with the unconditional.
It name internal because it is formed in structural components of a conditioned reflex. Conditional braking demands for development of certain time. This kind of braking concern угасательное, дифференцировочное, a conditional brake and late. Ugasatelnoe braking develops when the conditional irritant ceases to be supported unconditional, thus conditional reaction gradually disappears.
At the first presentation of a conditional irritant without the subsequent reinforcement conditional reaction is shown as usual. The subsequent presentations of a conditional irritant without a reinforcement start to cause rough reaction which then dies away.
Also conditioned-reflex reaction gradually disappears. Differentsirovochnoe braking is developed on the irritants close under the characteristic to a conditional irritant. This kind of braking underlies различенияраздражителей. By means of this braking from similar irritants what will be supported with an unconditional irritant, i.
