How the body's internal clock affects alertness

Regulation of arousal state by the suprachiasmatic clock

NIH-funded research University of California at Davis · NIH-11081791

This research explores how our natural body clock, located in a part of the brain called the SCN, controls how alert we feel, especially in conditions like Alzheimer's disease.

What this research studies

We are working to understand the specific brain pathways, cells, and connections that allow our internal clock to influence our level of alertness. This knowledge is crucial because many brain disorders, including depression and Alzheimer's disease, often involve severe problems with staying awake or feeling fatigued. Our goal is to uncover the exact mechanisms by which the SCN regulates arousal, which could lead to new ways to help patients with these challenging symptoms. We are focusing on specific neurons within the SCN and how they communicate with other brain areas involved in sleep and wakefulness.

Who could benefit from this research

Good fit: Patients experiencing arousal disorders, hypersomnia, fatigue, or those with neurodegenerative conditions like Alzheimer's disease may ultimately benefit from future treatments developed from this foundational research.

Not a fit: Patients without issues related to arousal, sleep-wake cycles, or neurodegenerative conditions are unlikely to directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to a deeper understanding and potentially new treatments for arousal disorders, hypersomnia, fatigue, and related symptoms in conditions like Alzheimer's disease.

How similar studies have performed: This research addresses a fundamental gap in understanding these specific brain circuits, suggesting a novel approach to a complex problem.
