[Changes in glutamate dehydrogenase activity in the neurons of the motor cortexof the cerebral hemispheres during light deprivation].
It has been shown that early light deprivation (keeping the rats for eight weeks from birth in a dark chamber) produces compensatory changes in the majority of pyramidal neurones in layers III and V of the brain motor area: significant enhancement of glutamatdehydrogenase activity activity in the bodies and processes of the neurones, increase of their volumes, augmentation of the number of neuroglial satellites with a high ferment activity. The revealed morphochemical changes, more pronounced in the layer V, are considered as a manifestation of enhanced functional activity of the coritcal end of the motor analyser, resulting from visual dereceptation.
