How inducing localized sleep-like brain rhythms in awake mice probes whether local sleep restores cognitive function after sleep loss.
Key Takeaways
- Optogenetic rhythmic stimulation induced NREM-like on-and-off activity in targeted brain regions
- Thirty-minute localized stimulation prevented sleep-deprivation tactile memory deficits in mice
- Stimulated regions showed reduced subsequent slow-wave activity, indicating lowered sleep need
