nervous and "" by mechanisms. a-adrenergicheskih receptors фентоламин, пирроксан; 5. where to buy nolvadex online In experiments on animals it has been shown, what, using g-oksibutirat sodium (ГОМК), it is possible to create deep гипотермию with preservation of warm activity at temperature more low 10? With, and also гипотермию with wakefulness preservation (to 10-20°С) at which the animal is capable to support a normal pose to keep reflex activity, thus on ЭЭГ bioelectric activity, characteristic for the wakefulness period is registered. Application ГОМК in a combination with гидрохиноном and glycerine allows to reach conditions long гипотермии (4 days at level 20 - 25°С). At research of mutual relations of excitation and braking in a brain bark it has been established that within several seconds after influence of a brake irritant the effect of positive conditional irritants amplifies. And on the contrary, after application of positive conditional irritants action of braking irritations amplifies. The first phenomenon is named by I. P.Pavlovym the negative induction, the second - a positive induction. At a positive induction in cages, adjacent with where braking was just caused, after cancellation of a brake signal there is a hypererethism condition. Thereof the impulses arriving to нейронам at action of a positive irritant, cause the raised effect. At a negative induction in cages of a bark, associates raised нейроны, there is a braking process. The negative induction limits иррадиацию excitation process in a brain bark. Negative induction it is possible to explain braking of conditioned reflexes by stronger extraneous irritations (external unconditional braking). Such strong irritation causes in a brain bark intensive excitation нейронов round which there is a wide zone of braking нейронов, grasping the cages raised by a conditional irritant.
