Abstract

A fine homeostasis of the brain extracellular fluid is required for the neural cells to fulfill their complex physiological fonctions. This homeostasis is achieved and controlled by several mechanisms which primarily involve the specific features of the blood-brain interfaces (BBI). These interfaces include the cerebral capillaries forming the blood-brain barrier (BBB), and the choroid plexuses. The latter are located in the lateral, third and fourth ventricles and, together with the meningeal arachnoid, control the exchange processes between the blood and the cerebrospinal fluid (CSF). In addition, the continuous secretion, circulation and resorption of CSF, a circulatory system which is specific to the central nervous system, also participates in the maintenance of cerebral homeostasis.
