Main outcome of study (acc. to author)

Microwave irradiation induces changes in electrical activity of the brain. The effect seems to be caused by a direct action of the penetrating field on the cortex. The summed electrical activity reaction consists of marked enhancement of slow waves. During this brain reaction, changes of pulse generation in cortical neuron populations occur. Changes of neuronal activity consisted in some increase of the mean values of interspike intervals and pronounced changes of the pattern of pulse flows.The various neuronal reactions appear to be the result of microwave exposure itself and to switching on and switching off to the field.
