We visited Stanford University to explore the ongoing research conducted by scientists in their labs. The focus is on understanding sleep and its implications for human health, with insights provided directly from the researchers.
Approximately 30% of people will face sleep issues at some point. These problems are closely linked to neuropsychiatric disorders, affecting 80% of autistic children and similarly impacting those with Parkinson’s and Alzheimer’s diseases. Current interventions for sleep disorders are not ideal, as sleeping pills pose health risks and drug approvals are lengthy.
The research team is working to understand the regulation of sleep, brain activity during sleep, and how to address disruptions in sleep patterns. A significant discovery involves identifying a mechanism behind fragmented sleep in older adults, which could lead to new drug therapies.
The work comprises three main areas. The first involves mapping neural circuits related to transitions between wakefulness and different stages of sleep using optogenetics, a technique pioneered by Karl Deisseroth at Stanford.
The second area investigates the purpose of sleep, particularly its potential role in repairing DNA damaged during waking hours. This hypothesis is being explored through collaborations with various labs.
The third branch aims to apply accumulated knowledge for practical use in humans through commercial products developed from these findings. One promising method identified is ultrasound for non-invasive neuromodulation targeting specific brain circuits important for sleep-to-wake transitions.
Researchers hope to fully understand the elements controlling sleep within the next two decades. The journey has been marked by significant progress over time.
“Step by step, we’ve made a huge amount of progress,” said one researcher. The passion for innovation and discovery continues to drive their work forward.
