Article Synopsis
- Exposure to short-wavelength light, like that from smartphones, can suppress melatonin secretion before sleep, impacting sleep quality.
- Limited studies have compared how this light affects sleep in adolescents versus young adults, revealing that while both groups experience melatonin disruption, adolescents recover faster.
- Despite the melatonin impact, neither age group showed significant changes in sleep-dependent memory consolidation or overall sleep architecture, suggesting the importance of avoiding screens before bed to maintain healthy sleep patterns.
Nonoscillatory measures of brain activity such as the spectral slope and Lempel-Ziv complexity are affected by many neurological disorders and modulated by sleep. A multitude of frequency ranges, particularly a broadband (encompassing the full spectrum) and a narrowband approach, have been used especially for estimating the spectral slope. However, the effects of choosing different frequency ranges have not yet been explored in detail.

Recommendations for the diagnostic procedure for insomnia and its comorbidities are: clinical interview (encompassing sleep and medical history); the use of sleep questionnaires and diaries (and physical examination and additional measures where indicated) (A). Actigraphy is not recommended for the routine evaluation of insomnia (C), but may be useful for differential-diagnostic purposes (A).

- The study explores how sleep affects motor adaptation, particularly in skills like typing, by examining brain activity during a new typing task on a mirrored keyboard.
- Results indicate that participants showed better performance after a full night of sleep compared to staying awake, along with changes in brain activity, specifically reduced beta power and lower spectral slopes during the task.
- Additionally, higher fast sleep spindle density after training was linked to improved motor adaptation, suggesting that sleep enhances the brain's ability to adapt to new motor tasks.
