Abstract

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.

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
