Abstract To study the effects of low-level microwave radiation (10 GHz CW), the compound eye of crayfish was irradiated. An eye was inserted into a waveguide and irradiated at a power of 1 mW for 1 minute. This power is below Japanese safety standards. The spontaneous discharge was measured with electrodes inserted into the optic nerve. The intervals of the spontaneous discharge during irradiation was compared with those of the control one. The amplitude of the waves and the mean value of the interspike intervals were not significantly changed, but the distribution of the intervals (variance) was changed by irradiation. At the beginning of irradiation, the variance decreased, but then increased and approached the value found without irradiation. This response is not a thermal effect and also differs from the response to light. The data were analysed by conventional methods and the power spectrum method.
