Summary
Various changes were observed in synaptic structures following irradiation in the dose of 450 to 600 r. These structures were changed from delicate rings into button-like, mace-like structures and nodules of large size. All types of synaptic structures are subjected to hypertrophy-axosomatic, axodendritic and axovasal. However, there is a considerable number of synaptic structures which remain intact. This points to the high plasticity of the nervous system. Changed synaptic structures, probably, cause alteration of reflexes with ensuing local and general disturbances.
