Ramelteon modulates gamma oscillations in the rat primary motor cortex during non-REM sleep by Airi Yoshimoto, Kotaro Yamashiro, Takeshi Suzuki, Yuji Ikegaya, Nobuyoshi Matsumoto

“…A neural-oscillation-based algorithm was used to classify the behavior of the rats into three vigilance states (e.g., awake, rapid eye movement (REM) sleep, and non-REM (NREM) sleep). Moreover, we investigated the region-, frequency- and state-specific modulation of extracellular oscillations in the ramelteon-treated rats. …”

Discovery of key whole-brain transitions and dynamics during human wakefulness and non-REM sleep by Stevner, A, Vidaurre, D, Cabral, J, Rapuano, K, Nielsen, S, Tagliazucchi, E, Laufs, H, Vuust, P, Deco, G, Woolrich, M, Van Someren, E, Kringelbach, M

“…This Hidden Markov Model (HMM) facilitated discovery of the dynamic choreography between different whole-brain networks across the wake-non-REM sleep cycle. Notably, our results reveal key trajectories to switch within and between EEG-based sleep stages, while highlighting the heterogeneities of stage N1 sleep and wakefulness before and after sleep.…”
