[Autoradiography of protein synthesis as a method of assessment of morphofunctional changes in brain structures].
A combination of two groups of autoradiography technique (for a hole brain and individual cells) was applied with using 3H-leucine to evaluate the changes of brain functional activity on the level as anatomical structures and as different type neurons. It was found that Wistar rats with lowered motor activity induced by 3-4 weeks treatment with L-DOPA 100 mg/kg displayed the motor nuclei of the brain stem the cerebellum as highly labelled structures and the motor cortex and n. caudatus as feebly ones in comparison with control. However, a quantitative assessment of silver grains over the neurons of layers III and V of motor cortex and n. caudatus showed not only a significant increase of labelling, especially in neurons of layer V on 174%, in comparison with control but revealed unequal labelling of different type neurons. It was concluded that the applied two groups of autoradiography technique can be a useful approach to assess the brain functional activity.
