Abstract
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.
摘要
研究了大鼠大脑皮质细胞外间隙体积对周围重复刺激的反应。细胞外间隙的体积及其变化通过改良的四电极阻抗法进行评估。结果表明，大脑皮质诱发的电活动伴随着细胞外间隙体积3%至5%的减小。
