Changes in the volume of the intercellular space of the cerebral cortex in conditions of peripheral stimulation in rats.
Changes in the volume of the intercellular space of the rat cerebral cortex in response to peripheral repetitive stimulation were studied. The volume of the intercellular space and its changes were assessed by a modification of the four-electrode impedance method. The results suggest that evoked electrical activity in the cerebral cortex was accompanied by 3-5% decreases in the volume of the intercellular space.
