[Structural changes of synaptic membranes under the action of specific antisera using the spin probe technique]

The spin probing technique was used to study the interaction of preparations of rat cerebral cortex synaptic membranes with specific antisera. It was found that the fluidity of membrane matrix largely depended on the nature of physiological processes involving synaptic membranes in vivo. The supramolecular structure of synaptic membranes isolated from the brain of trained animals differed from that of controls. Differences in the properties of synaptic membranes were also revealed during their incubation with specific antisera. The data obtained are interpreted in terms of immunochemical theory of memory and training.
