Neuroendocrinology is the domain of biology that is concerned with the study of the interaction between the nervous system and the endocrine system. In the process of neuroendocrine integration, the nervous and endocrine systems act together in order to control the physiological processes of the human body. For understanding and treating neurobiological brain disorders, neuroendocrinology is used as an essential part. The neuroendocrine system is the tool through which the hypothalamus maintains homeostasis that helps in regulating metabolism, eating, reproduction, osmolarity, blood pressure and drinking behavior. The four main neuroendocrine systems are hypothalamic-pituitary-adrenal axis, hypothalamic-pituitary-thyroid axis, hypothalamic-pituitary-gonadal axis and hypothalamic-neurohypophyseal system. This book contains some path-breaking studies in the field of neuroendocrinology. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. This book is appropriate for students seeking detailed information in this area as well as for experts.
