Abstract
Glucose transport across the blood-brain barrier (BBB) has been shown to be a carrier-mediated, saturable process of the facilitated diffusion type (4). The cerebral steady-state glucose concentration depends on the kinetic properties of transport and is lower than in blood. Direct measurement of brain glucose is not possible in humans by non-invasive techniques using radioactive tracers because the signal of labeled glucose cannot be distinguished from that of its metabolic products.
