The central nervous system (CNS), which comprises the brain and spinal cord, serves as the core regulatory hub for maintaining homeostasis and coordinating diverse physiological functions. These functions include interoception, cognition, and social behavior. The intricate architecture and extensive connectivity of the CNS enable integration of multi-system responses, thereby ensuring bodily stability and adaptability. The CNS exerts profound regulatory influences on fundamental life-sustaining processes and higher-order cognitive and social functions. This is mediated by distinct neural circuits and molecular mechanisms. CNS dysfunction is strongly associated with the pathogenesis of neurological disorders (Alzheimer's disease, Parkinson's disease, stroke and epilepsy), metabolic diseases (obesity and diabetes), and cardiovascular conditions (hypertension and atherosclerosis). Given the pivotal role of the CNS in both physiological regulation and disease progression, a comprehensive understanding of CNS mechanisms is critical for identifying therapeutic targets. This review systematically examines the regulatory functions of the CNS in physiology and disease. Moreover, this review analyzes the underlying molecular and circuit-level mechanisms, and discusses potential therapeutic strategies. By elucidating the systemic interactions of the CNS, this study aims to highlight its potential as a target for innovative interventions in disease prevention, diagnosis, and treatment.
