Circumventricular organs that information neurally to other brain regions. Through their neural circuitry, they provide direct information to the autonomic nervous system from the systemic circulation. The secretory organs include the subcommissural organ (SCO), the pituitary gland, the median eminence, and the pineal gland. These organs are responsible for secreting hormones and glycoproteins into the peripheral blood using feedback from both the brain environment and external stimuli. All of the circumventricular organs, except the subcommissural organ, contain extensive vasculature and permeable capillaries which define a sensory and secretory system within the brain. Furthermore, all CVOs contain neural tissue, enabling a neuroendocrine role.
