Impulse noise causes maximum increase of excitability of the hippocampus 1 hour after the effect, whereas with application of stable noise, maximum increase of excitability is noted after 3 hours. Under conditions of prolonged chronic experiment, impulse and stable noise have a different effect on the functional state of the hippocampus. A stable noise stimulus causes persistent depression of the hippocampus even after the 1st month of the test. Impulse noise causes an increase of excitability of the hippocampus at the end of the chronic test. Immediately after the alternate effect of impulse and stable noise, at all stages of the chronic test, excitability of the hippocampus was increased.
