Researcher from University of Surrey Reports on Findings in Health and Medicine (Closed-loop auditory stimulation targeting alpha and theta oscillations during REM sleep induces phase-dependent power and frequency changes).

A recent study conducted by researchers from the University of Surrey in the United Kingdom explores the use of closed-loop auditory stimulation (CLAS) to modulate alpha and theta oscillations during rapid eye movement (REM) sleep. The study involved recording high-density electroencephalogram (EEG) data from 18 healthy young adults during an extended overnight sleep period. The results showed that CLAS induced phase-dependent changes in power and frequency of REM sleep rhythms, suggesting that modulation of these oscillations could impact brain function during this sleep stage. This research provides a new approach to investigating the role of REM sleep in brain function. [Extracted from the article]
