[Pulse flows of cortical neuron populations exposed to microwaves: interspike intervals]

In unanesthetized nonimmobilized rabbits pulse flows of populations of cortical neurons were investigated prior, during, and after 1-min microwave irradiation (wavelength 37.5 cm, power density 0.2-0.3; 0.4; 0.5; and 40 mW/cm2). Changes of interspikes intervals occurred through these exposure. Shifts as the decrease of mean values of interspike intervals predominated under irradiation of 0.2-0.3 and 0.4 mW/cm2. Shifts of the opposite direction prevailed under irradiation of 0.5 and 40 mW/cm2. The least changes of the interspike intervals took place under irradiation of 0.4 mW/cm2.
