Chronic Hypoosmolality Induces a Selective Decrease in Magnocellular Neurone Soma and Nuclear Size in the Rat Hypothalamic Supraoptic Nucleus

Abstract The magnocellular neurones of the hypothalamo‐neurohypophysial system (HNS) play a vital role in the maintenance of body homeostasis by regulating oxytocin (OT) and vasopressin (VP) secretion from the posterior pituitary. During hyperosmolality, OT and VP mRNA levels are known to increase b... View More
