RESUMO
In chronic experiments on cats, automatic regulation of polarizing current, monitored with the EEG changes, aided to study elements of the cerebral selfregulating system. The method proved effective for influencing the functional state of the structures to be regulated which revealed itself in long-lasting shifts of theta-rhythm, in changes of excitability and readjustment of EPs. Three types of connections between the temporal cortex and a number of cerebral modulating structures: rigid (positive and negative) and flexible those, were revealed. The active inhibition was accelerated with the bioregulated micropolarization of temporal cortex and hypothalamus on extinction of alerting response.

With the aid of the EEG special statistical analysis, micropolarization of the temporal cortex of hypothalamus was shown to entail abrupt alterations of the theta-, alpha-, and beta-rhythms in the temporal and motor cortex, hypothalamus, and the midbrain RF. The changes of the biorhythms (their correlation, thresholds of occurring, connection of the local and distant shifts) are regarded as reflecting some fine regulation of the structures' functional condition as well as mutual influences of the cortex and the deep brain structures which tell on modulation of mnemic processes.
