How brain circuits and glia control sleep
Official title: Sleep Neurobiology and Circuitry
Funded at Ralph H Johnson VA Medical Center · NIH-11212785 · Data updated 2026-11-12
This work uses tiny brain cameras to watch neurons and glial cells to understand how they drive sleep and wakefulness in ways that could matter for people with sleep problems and Alzheimer's disease.

Who could benefit from this research
✓Could help
People with chronic sleep disturbances or those with early-stage Alzheimer's disease or at high risk for Alzheimer's would be the most relevant group for this line of research.
✕Less likely to help
People with conditions unrelated to sleep or Alzheimer's, or those needing immediate clinical interventions, are unlikely to receive direct benefit from this basic brain imaging work.
What this research studies
Researchers will use microendoscopy (tiny, implantable microscopes) to image activity of neurons and astrocytes in a deep brain region called the zona incerta while animals cycle through wake, NREM and REM sleep. They will compare glial activity patterns to known wake-active and REM/NREM-max neurons to see whether glia are active at the same times or have different roles. The project has four specific aims that test when and where glia are active and how that activity influences sleep states. Results may point to new biological targets for treating sleep disruption linked to Alzheimer's disease.
Why it matters
Potential benefit: If successful, this research could point to new ways to treat sleep problems and potentially slow brain changes related to Alzheimer's disease.
How similar studies have gone: Previous animal work shows astrocyte activity can increase sleep, but mapping glial activity across wake, NREM and REM in the zona incerta with microendoscopy is a newer approach.
