Simultaneous measurement of the electrolytic conductivity of the cerebrospinal fluid and the blood serum in newborns has revealed a concentration gradient suggesting an active transfer of electrolytes into the liquor space. The extent of this concentration drop is regarded as expressing the functional capacity of the blood-liquor barrier. Comparative investigations in healthy older children shown that constant values, corresponding to the adult age, are reached approximately at the end of the first year of life.
对新生儿脑脊液和血清的电解电导率进行同步测量，结果显示存在浓度梯度，这表明电解质会主动转移至脑脊液间隙。这种浓度下降的程度被视为血脑屏障功能能力的体现。对健康大龄儿童的对比研究表明，大约在一岁末时会达到与成年人相当的恒定值。
