[The direct action of high doses of gamma quanta and neutrons of different energies on the sympathetic ganglion neurons in the frog].
Irradiation of isolated frog sympathetic ganglia IX-X with high doses caused a long-term depolarization of a single ganglion cell and increase of synaptic activation threshold. The radiation effects observed were not accompanied by the transmission failure. The authors suggest that the changes in the synaptic mechanisms play a minor role in the development of the CNS syndrome.
