REM Sleep Iota Oscillations Across the Lifespan
Summary
In 937 high-density sleep EEG recordings from people aged 7 to 70, 'iota' oscillations at 25–40 Hz appeared during REM sleep at every age. They became less common with age, from 88% of children to 44% of older adults. A twin dataset suggests they are highly heritable.

Facts
- id: F1 claim: Iota spectral peaks in REM sleep were between 25 and 40 Hz, slightly faster than in wakefulness (25–35 Hz). confidence: medium date: 2026-11-02 sources: [S1] license: CC BY 4.0
- id: F2 claim: Iota power rose with REM duration and across later sleep cycles. confidence: medium date: 2026-11-02 sources: [S1] license: CC BY 4.0
- id: F3 claim: Prevalence fell with age, from 88% in children to 44% in older adults; peak bandwidth was narrow in children and broad in older adults. confidence: medium date: 2026-11-02 sources: [S1] license: CC BY 4.0
- id: F4 claim: Twin data showed high heritability of all iota peak properties except bandwidth. confidence: medium date: 2026-11-02 sources: [S1] license: CC BY 4.0
- id: F5 claim: Whether narrowband and broadband iota are functionally equivalent is stated by the authors as unresolved. confidence: medium date: 2026-11-02 sources: [S1] license: CC BY 4.0
