Seven small circumventricular organs (CVOs) of the brain have modifications in the anatomy of their neuropil, ependyma, or vasculature, which suggest that they may be involved in communication between brain and body. This communication may take the form of signals from brain to body via the systemic circulation (neurohemal) or from body into the brain (hemoneural). Of these windows of the brain, evidence for and the anatomical substrate for neurohemal communication is well established in the case of median eminence (ME), neurohypophysis (NP), and the pineal gland (PG); hemoneural communications may take place in the subfornical organ (SFO), the organum vasculosum laminae terminalis (OVLT), and the area postrema (AP). The subcommissural organ (SCO) is the least well understood with regard to its participation in this mode of brain—body communication. |
