Main outcome of study (acc. to author)

It has been shown that microwave irradiation of an unanesthetized rabbit's head produces shifts in cortical neuron activity. The microwaves have practically no influence on the mean frequency of neuronal discharge. But they affect considerably spike flow pattern of cortical neuron populations. In particular, the discharge peaks decreased in number and increased in duration, and the total time they took in the spike flow also increased.
