A cross-section of a human brain showing the structure of an astrogate membrane. On the left side of the image there is a diagram of the structure which shows the structure and its functions. On the top right side there are two illustrations of the brain one showing the pericycle and the other showing the high and low levels of drug accumulation. The image also shows a diagram that shows the interaction tight junctions between the active efflux transport and the lipophilic diffusion of the endothelia cell. The active tight junction is responsible for the formation of the lipoplastic diffusion which helps to regulate the flow of blood and nutrients in the brain. The high level of the drug accumulation is the highest level while the low level is the lowest level. The image also includes a bar graph that shows that the drug concentrations are higher than the high levels.
