Using light and sound to gently tune brain activity
Cell Type and Circuit Mechanisms of Non-Invasive Brain Stimulation by Sensory Entrainment
This project uses patterned flashes of light and tones to gently change brain rhythms with the goal of helping memory and reducing signs of brain disease.

What this research studies
Researchers use timed light flicker and auditory tones (often near 40 Hz) to synchronize brain activity and study how different brain cells and circuits respond. Most experiments combine detailed computer models with lab work in mouse cortex to track changes in neurons, microglia, and blood flow. The team links those cellular and circuit changes to memory performance and clearance of disease-related markers in animal models. Insights from these studies aim to guide safe, non-invasive sensory stimulation approaches that could be adapted for people with memory problems or neurodegenerative disorders.
Who could benefit from this research
Good fit: In eventual human trials, ideal candidates would likely include people with memory impairment or early-stage neurodegenerative conditions such as mild cognitive impairment or Alzheimer's disease.
Not a fit: People without neurological conditions, those with very advanced disease, or individuals with photosensitivity or severe hearing loss may not receive benefit from sensory stimulation approaches.
Why it matters
Potential benefit: If successful, the work could enable simple, non-invasive light or sound therapies that improve memory and reduce markers of neurodegeneration in patients.
How similar studies have performed: Animal studies using 40 Hz sensory stimulation have shown improved memory and clearance of disease markers, but human evidence is limited and the detailed mechanisms remain novel.
