Dotted arrows: diffusion of water or solutes occurring between brain capillaries, CSF, and nervous tissue a across the blood–brain barrier; b across the epithelium of the choroid plexus; c across the ventricular ependyma; d across the pia–glial membranes at the surface of the brain and spinal cord, and e and f across the cell membranes of neurons and glial cells.
