[Changes of extracellular space volume of the cerebral cortex during peripheral stimulation in rats].
Changes of extracellular space (ECS) volume evoked by peripheral repetitive stimulation were studied in the cerebral cortex. Extracellular volume and its changes were measured by electrical impedance method with the fourth electrode scheme. Measurements indicate that the dynamic changes of ECS volume accompany electrical activity of cortex and have value 3-5%.
