[The effect of high energy irradiation on the membrane potential and impulse activity of neurons in the brain of Helix pomatia].
In electrophysiological experiments with a preparation of the isolated Helix pomatia brain, a study was made of the effect of pulsed irradiation with high-energy electrons (20 MeV) on membrane potentials and pulse activity of "silent", pacemaking and postsynaptic neurons. It was shown that after irradiation with 150 and 300 Gy (dose rate 5 Gy/s and pulse frequency 50 Hz) "silent" neurons retain their excitability. Pacemaking neurons responded to radiation by a drastic increase in spontaneous pulse activity followed by its transfer to a clipped then to an irregular one. At the same time, the discharge frequency increased in the postsynaptic neurons.
