Yuta Senzai & Massimo Scanziani discovered that the direction and amplitude of rapid eye movements during REM sleep reveal the direction and amplitude of the ongoing changes in virtual head direction. Image credit: Yuta Senzai & Massimo Scanziani, doi: 10.1126/science.abp8852.

Study: Rapid Eye Movements during REM Sleep Mimic Gazes in Dream World

Sleep includes phases characterized by rapid eye movement (REM) that were known to be associated with dreaming. But are these eye movements related to...

Deperrois et al. suggest that generating new, virtual sensory inputs via adversarial dreaming during REM sleep is essential for extracting semantic concepts, while replaying episodic memories via perturbed dreaming during NREM sleep improves the robustness of latent representations.

New Research Illuminates Dominant Functions of Sleep and How They Change Through Our Lives

Sep 22, 2020 by News Staff

Before the age of 2 or 3 years, the human brain grows very rapidly and, during REM sleep, is busy building and strengthening synapses. After 2 or 3 years,...

Ingestion of a prebiotic diet improves undisturbed NREM sleep, promotes REM sleep rebound after stress exposure, and prevents stress-induced reductions in gut microbial alpha diversity. Image credit: Sabrina Ripke.

Dietary Prebiotics Can Improve Sleep and Fight Stress: Study

Mar 4, 2020 by News Staff

Dietary prebiotics can improve sleep and boost stress resilience by influencing gut bacteria and metabolites (biologically active molecules) they produce,...

The acetylcholine pathway has been proposed to be important for wakefulness and REM sleep, but genetic evidence has been missing. Using a knockout of acetylcholine receptor genes, Niwa et al show that Chrm1 and Chrm3 double knockout chronically diminishes REM sleep to an undetectable level and causes a severe short-sleep phenotype.
