Behavioral reactions (open-field test, elevated plus-maze, pain stress, and feeding behavior) were studied in various periods after clinical death caused by circulatory arrest for 10 or 15 min. We revealed two different phases of behavioral changes:

We analyze the role of the theory of functional systems for human general pathology and the necessity of integration of this theory with the concepts of pathological and ambivalent systems. Multiple (qualitatively heterogeneous) nature of system-form

Experiments on rabbits with compartment syndrome of the leg showed that the main pathogenetic factors of muscle injury are postischemic contracture leading to extravascular microcirculatory disorders and tissue necrosis(early postcompression period)

Neglect of probability prognosis orients the theory of functional systems to description of rigidly determined forms of behavior (congenital behavior, frontal syndrome, etc.). The authors suggest an original concept for analysis of behavior under con

A concept of functional isolation of the heart from nervous effects as a mechanism of heart adaptation to extreme states has been formulated. In moderate hypoxia, isolation of the cardiovasomotor center from nonhypoxic afferention provides the compli

The rats survived 10- or 15-min systemic blood flow arrest were exposed to various extreme factors within the following 2 months. It was found that the processes leading to functional isolation of CNS play a protective role: they moderate behavioral

Operant conditioning under conditions of uncertain behavioral environment was accompanied by a significant elevation of blood corticosterone, high exploratory activity, and increased resistance to hypoxia. The blood content of corticosterone and expl
