Protein content in rat brain neurons predisposed and resistant to emotional stress

Abstract

Protein content was measured by interferometry in the cerebral neurons of August rats predisposed to emotional stress and Wistar rats resistant to it. Protein content was 16-18% lower in the neurons of the third and fourth layers of the sensorimotor cortex and 51% higher in the caudate nucleus neurons (cerebral subcortical nodes) of August latS than in Wistar rats. This indicates an inversion in protein distribution in the cortex and subcortex of August rats which are characterized by typical protein content in different types of neurons and apparently by peculiar cerebral structure and fimction.

Morphocytochemical characteristics of cerebellar neuronal populations in fishes with various ambulatory activities

“…The content of proteins was higher in nuclei of granular layer cells. The concentration of proteins reflects functional activity of nervous cells [3,5,10]. Similarly directed shifts in the concentrations of dense substances in the cytoplasm and nuclei (in our experiments this was typical of all neuronal populations) indicate stable changes in the protein pool of cerebellar neurons.…”

“…However, histo-and neurochemical peculiarities of cerebellum of aquatic vertebrates (especially lower animals) received little attention. Only the brain stem, cortex, and subcortical ganglia of mammalian brain were studied in this aspect [5,9].A comparison of morphocytochemical peculiarities of cerebellar neuronal populations in fishes of …”
