[Rearrangement of bioelectric activity of the brain during adaptation to chronic hypokinesia].
The study shows that chronic hypokinesia (7-8 months) in rats, analogous to that in humans, causes constant reduction in activation level and results in the development of rearrangements in brain slow bioelectric activity. The rearrangements initiate decrease of the general level of brain activity and compensatory rise of its response to environmental signals. A likely mechanism of the rearrangements of the first type can be characterized by amplification of recurrent stopping processes and that of the second type by raising efficacy of the synaptic system functioning.
