FUNDING PROGRAM FOR NEXT GENERATION WORLD-LEADING RESEARCHERS Project Title: Elucidation of brain circuitry mechanism for emotion–autonomic signaling to conquer stress disorders Name: Kazuhiro NAKAMURA Institution: Kyoto University 1. Background of research In today’s stressful society, increasing numbers of patients suffer from various stress disorders. These disorders are developed by strong and chronic signaling from the stress-mediating brain systems to the homeostatic brain systems, such as autonomic regulatory systems for body temperature and blood pressure. However, the brain mechanism underlying the stress signaling is unknown and therefore, there is no ultimate approach to cure stress disorders. 2. Research objectives The goal of this study is to elucidate how psychological stress signals affect the homeostatic brain systems. This basic research will provide important information to understand the mechanisms underlying the development of stress disorders. 3. Research characteristics (incl. originality and creativity) This study utilizes animal models of stress disorders in combination with innovative techniques to manipulate activities of specific neural wirings in brain circuits to elucidate the core neural mechanisms of hyperthermia as well as hypertension that are evoked by stress signaling from the stress-mediating brain systems to the homeostatic brain systems. 4. Anticipated effects and future applications of research The elucidation of the fundamental mechanisms underlying the stress-induced hyperthermia and hypertension in this study will provide important information to understand the core mechanism that is common to the development of various stress disorders. 「Emotion–autonomic signaling」 Emotion–Autonomic signaling Psychological (emotional) stress ??
