[The electrical activity of symmetrical areas of the rat cerebral cortex during the use of a low-intensity UHF field].

Electrical asymmetry of electrograms of the rat symmetrical brain areas was decreased under the UHF irradiation of the animals. Non-modulated UHF field increased the 1.5 and 6 Hz rhythms in the left hemisphere, whereas modulated UHF field decreased the 1 Hz rhythm in the right hemisphere.

[Changes in the electrical activity of the rat brain during the central administration of different doses of GABA agonists and antagonists].

The changes in the frequency content of electrograms of the optic cortical area and deep structures of the brain (putamen, dorsal hippocampus, medial part of the hypothalamus) were studied during intraventricular introduction of various doses of GABA-receptor agonists (GABA, muscimol, baclofen) and antagonist (bicuculline). The latter was found to affect the overall electrical activity slightly regardless of the dose. When muscimol and baclofen were injected, the greatest EG effect was observed at 1.
