Median Preoptic Nucleus (Mnpo) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Median Preoptic Nucleus (MnPO) is a key hypothalamic structure involved in thermoregulation, sleep-wake regulation, and autonomic control. Located in the preoptic area of the anterior hypothalamus, the MnPO serves as a central hub for integrating thermal and osmotic signals.
