New paper! 🧠💤 www.nature.com/articles/s41... Led by Pauline Dodet - @dreamteamicm.bsky.social We show that #sleep stage mixing predicts poor prognosis in #Parkinson. Stage mixing = intrusions of wake-like activity during sleep, and vice versa. Estimated with hypnodensities extracted from PSG.

🧠🧪 New paper in #NCONSC 🧠🧪 What if people who seem unconscious (e.g., Disorders of Consciousness, DoC) could still dream or experience mind wandering? We explore this possibility in a new review: academic.oup.com/nc/article/2... With Jasmine Walter and Jennifer Windt! #consciousness #dreaming

Abstract. Fluctuations in the presence, experiential quality and contents of consciousness occur naturally during sleep and wakefulness and are core featur

Slow waves during sleep are fundamental for neural homeostasis and are impaired in neurodegenerative diseases. But what about sleep-like slow waves during wakefulness? Are these slow waves altered in Parkinson's disease? Are these slow waves uncovering psychosis?

Sleep-like slow waves during wakefulness uncover a malignant form of Parkinson’s disease

Slow waves during sleep are fundamental for neural homeostasis, metabolic regulation, and waste clearance, and are known to be altered in neurodegenerative diseases. Sleep-like slow waves (SLSW) have ...

You’ve probably heard of delta, theta, alpha, sigma, beta and gamma brain waves. But have you ever come across iota? If not, here’s your chance: new paper from @snipeso.bsky.social, current postdoc in our team, introducing a novel class of brain waves (iota), specific to wakefulness and REM sleep! 🥳

Iota oscillations made it past peer review! Welcome to the zoo of sleep oscillations 😊 journals.physiology.org/doi/full/10....

Recording EEG without ECG or with noisy ECG? This open-source tool by Pierre Champetier (postdoc in our team) & Maximilien Chaumon (M/EEG research engineer at the @institutducerveau.bsky.social ) might be just what you need! (Still in development, release in a few weeks/months)
