This study shows that aging and Alzheimer's disease are linked to changes in REM sleep delta waves, which are associated with memory decline and amyloid-beta and tau accumulation.

The paper shows that tau pathology in the frontal lobe impairs slow wave propagation, leading to memory deficits in humans.

This study shows that personalized transcranial alternating current stimulation (tACS) improves sleep duration and reduces sleep onset latency compared to fixed-frequency tACS and a control condition.

This study shows REM sleep recalibrates excitation/inhibition balance, predicting memory consolidation success in humans.

This paper introduces an automated sleep staging tool with high accuracy, validated on diverse populations, and provides an open-source, free, and user-friendly solution.

This study shows sleep loss increases blood pressure independently of heart rate, disrupts brain connectivity regulating vascular tone, and links mood changes to these effects, highlighting brain-body-mood interactions in cardiovascular risk.

The paper identifies the 1/f spectral slope as an electrophysiological marker that distinguishes wakefulness from sleep and anesthesia by reflecting changes in excitation-inhibition balance.
