Hormonal Influences on Brain Plasticity: III. Peptide Hormones
This chapter examines the role of peptide hormones in the regulation of neural mutability and the involved cellular and molecular mechanisms. It first considers the effects of vasopressin and oxytocin—hormones released in the neurohypophysis. It then analyzes the plastic actions of corticotropin-releasing hormone, prolactin, gonadotropin-releasing hormone, insulin, growth hormone, insulin-like growth factor-I (GF-I), erythropoietin and angiotensin. Finally, the chapter considers the effects of feeding hormones leptin, ghrelin, and glucagon-like peptide-1 on neural plasticity. These hormones exert important plastic actions on the organization of neuronal circuits involved in the control of food intake and energy balance, but also promote plastic remodeling of cognitive brain areas.
Keywords: corticotropin-releasing hormone, prolactin, gonadotropin-releasing hormone, insulin, growth hormone, erythropoietin, angiotensin, glucagon-like peptide-1, vasopressin, oxytocin, leptin, ghrelin
