[The ultrastructure of the emotiogenic structures of the rat brain in a neurosis-like state acquired on a background of hypokinesia].
The disorder of the higher nervous activity was induced in rats, situated for 90 days under the conditions of hypokinesia. Was investigated the ultrastructure of some limbic regions: the central and the lateral nuclei of the amygdala and area 24a of the cingulate cortex. Ultrastructural changes were seen in neurons, synapses, and the glial elements of the regions under study. The main characteristic of these changes was found to be the presence of morphological criteria of high functional activity in the majority of neurons and synapses. The results were compared with the previous data on the hypokinetic structural changes in the absence of a neurosis. In the latter case hypokinesia caused, on the contrary, the diminution of the functional activity in the majority of neurons and synapses under study.
