Neuroendocrinology, the discipline concerned with how the nervous system controls hormonal secretion and how hormones control the brain, is pivotal to physiology and medicine. Neuroendocrinology has disclosed and underpins fundamental physiological, molecular biological and genetic principles such as the regulation of gene transcription and translation, the mechanisms of chemical neurotransmission and intracellular and systemic feedback control systems. Reproduction, growth, stress, aggression, metabolism, birth, feeding and drinking and blood pressure are some of the bodily functions that are triggered and/or controlled by neuroendocrine systems. In turn, neuroendocrine
