Circumventricular organs are specialized, highly blood-rich tissues found mainly along the midline of the brain’s ventricular system, extending from the forebrain to the hindbrain. Unlike most brain areas, they do not have a typical blood-brain barrier and have capillaries with small openings, and they include cells involved in chemical sensing or neurosecretion.
