[Dynamics of the early ultrastructural changes in sensorimotor cortical neurons of the rat brain after exposure to high doses of gamma-neutron radiation].

At early times (15 min to 6 h) after whole-body gamma-neutron irradiation of mature rats with a dose of 10 Gy reactive changes occur in neurons of the sensimotor cerebral cortex which can be interpreted as a manifestation of the enhancement of functional and metabolic activity of nerve cells followed by inhibition thereof.
