Circumventricular organs is also hypothesized that the VOLT may be the mechanism through which pyrogens function to initiate a febrile response in the CNS. Finally, VOLT neurons have been observed to respond to temperature changes indicating that the organum vasculosum of the lamina terminalis is subject to different climates. The subfornical organ is a sensory CVO situated in the lamina terminalis and lacking the BBB, the absence of which characterizes the circumventricular organs. Protruding into the third ventricle of the brain, the highly vascularized SFO can be divided into 3–4 anatomical zones, especially by its capillary density and structure. The central zone
