Female rats of the Wistar strain with a mean weight of 222 g were exposed to 96 dB sound according to L. V. Krushinsky. Their eyes were irradiated with a high UV dose in order to reveal potential disorders in high nervous activity. After 3, 7 and 35 days of exposure to UV irradiation at a dose of 10 kJ/m2 with a maximum wavelength of 302 nm the following changes were observed: the amount of "inhibited" rats grew, the latency time of I degree attacks and the duration of inhibition states increased, and the duration of seizure fits decreased. It is postulated that inhibition effects may enhance and stimulation effects may attenuate as a result of reduction of afferent pulses entering the central nervous system from the visual organ due to keratoleukoma.
