[Localization of ATPase in the cerebral cortex and its role in the functional activity of neurons].

By analogy of defensive conditioned reflex formation in rats using a cytochemical method, dependency of localization and concentration of the product of ATP-ase activity on neuronal and synaptic functional activity has been demonstrated. It corresponds to the notion that only a part of the cortical cells are simultaneously at the state of structural-functional activity. The experimental data demonstrate that the CNS excitation in the animals during the process of learning is connected with increasing ATP-ase activity in ultrastructures of the nucleolus, pericaryon and synapses of some neurons participating in the formation of trace processes in the brain.
