Previous findings suggest a negative correlation between slow oscillations (SO) in posterior brain regions and dreaming. Here we use a precise closed-loop auditory stimulation (CLAS) procedure to causally test whether slow oscillations suppress dreaming. Our results show that boosting posterior SO during NREM sleep decreases the likelihood of dreaming as compared to no SO boosting. This study provides the first causal evidence for the neural correlates of dreaming.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
