Dreaming conundrum

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Dreaming, a common yet mysterious cognitive phenomenon, is an involuntary process experienced by individuals during sleep. Although the fascination with dreams dates back to ancient times and gained therapeutic significance through psychoanalysis in the early twentieth century, its scientific investigation only gained momentum with the ...

EEG Brain Rhythms During Resting‐State Wakefulness and Sleep in Elderly Expert Meditators

Journal of Sleep Research, EarlyView.
Compared to controls, elderly expert meditators exhibited (1) more preserved resting‐state brain activity, (2) less altered sleep architecture, and (3) EEG features indicative of heightened cognitive states during NREM sleep. Importantly, several of the metrics that differed between groups also showed consistent correlations with meditation expertise ...

Sleep Slow Wave‐Bistability and the Connection Between the Sleeping Brain and the Environment—Neurobiological Considerations

Journal of Sleep Research, EarlyView.
Bistability is an inherent working mode of NREM sleep. Those bistable patterns ‐ sleep slow waves, K‐complexes, and the cyclic alternating pattern (on a longer, several seconds' time‐scale) ‐ have a double function; they protect sleep and provide an interface between the brain and the environment for information‐transfer during sleep.
