[Dynamics of protein concentration in the neurons of a chronic "mirror" epileptiform focus].

Protein content in the neurons of layers III and V in the rat brain anterior-parietal cortex and the lateral thalamic nucleus was studied 11 and 63 days after cobalt implantation. In the course of the experiment, protein content increased by 44--49% in the neurons of layer III and decreased by 24--32% in the thalamic neurons. In small and large pyramids of layer V, protein content decreased by 21--28%, 11 days after cobalt implantation, and approached normal content by the 63rd day. It was concluded that according to morpho-functional characteristic of certain neuronal types (associative, in layer III, predominantly efferent, in layer V and associative neurons in subcortical formations of the lateral thalamic nucleus) their protein changes in response to convulsive activity were different.
