[Early changes in the ultrastructure of axodendritic synapses in the rat sensorimotor cortex following whole-body irradiation with high-dose fast neutrons].
Changes in morphometric parameters have been established in axodendritic synapses of sensorimotor cortex of adult mature rats exposed to neutron irradiation. Neutron irradiation dose and summarized dose rate were 10 Gy and 0.35 Gy, respectively. The changes were observed 0.25, 1, 3, 6 and 24 hours after irradiation. The observations suggest an increase in synaptic activity, with the range of irradiation action and functional characteristics decreasing in subsequent time periods.
