title: [Changes in response of neurons in visual area of cerebral cortex of rabbits to flashes of light under the influence of low-intensity physical factors of non-ionizing nature].
abstract: The effect of various physical factors (SM F: 460 O; microwave EMF: 6 GHz, continuous mode, 200 microW/sm2; sound: clicks of 50 Hz, 6 db above a threshold of EEG response) on responses of neurons in visual area of cerebral cortex of rabbits to light flashes (1 Hz, 1 ms, 0.62 J) has been studied in experiments on 27 rabbits. The character of changes depended on the indicators for a background and for the response to the isolated action of light. Inhibition, rather than activation, was observed at a significantly higher initial frequency. Effect of the factors of magnetic nature was similar to the action of sound (inadequate irritant for the visual area). Inhibitory reactions were observed more frequently (significant result for the group of neurons), with their amplification at a combined action of irritants (SMF and microwave EMF; SMF and sound). The basic character of changes was limited to the drop in the pulsation frequency at the first phase of activation and to the increase in the latent periods of the first and second active phases. Other indicators for reaction to light flashes actually didn't change.
