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 dysfunction due to genetic or other deficits can lead, for example, to infertility, impotence, precocious or delayed puberty, defective or excessive growth, obesity and anorexia, Cushing’s Syndrome, hypertension or thyroid disorders. These as well as neuroendocrine tumors are some of the themes covered in the 36 chapters of the Handbook. Drafted by internationally acknowledged experts in the field, the Handbook chapters feature detailed up-to-date bibliographies as well as "how do we know?" call out sections that highlight the experimental or technical foundations for major concepts, principles, or methodological advances in each area. Aimed at senior undergraduate and graduate students, post-doctoral fellows and faculty in neuroscience, medicine, endocrinology, psychiatry, psychology and cognate disciplines, the Handbook of Neuroendocrinology satisfies an unmet need that will prove useful at the laboratory bench as well as in the office.
