Sleep stage mixing is associated with poor prognosis in early Parkinson’s disease - npj Parkinson's Disease npj Parkinson's Disease - Sleep stage mixing is associated with poor prognosis in early Parkinson’s disease

New paper! 🧠💤

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.

The @dreamteamicm.bsky.social has launched an online survey about the things you experience when you fall asleep!

Everyone is different, so we need you to tell us!
It will take only 20 minutes, but it will mean a lot to dream researchers like us!

La @dreamteamicm.bsky.social vous propose une enquête (20 min) sur ce qui ce passe dans votre tête quand vous vous endormez !

Parlez-en autour de vous ! Chacun a sa façon de s'endormir !

Et comme on n'est pas des devins, on a besoin que vous nous racontiez vous-même !

Do individuals with disorders of consciousness dream and mind wander? Implications for improving diagnosis and understanding patient wellbeing Abstract. Fluctuations in the presence, experiential quality and contents of consciousness occur naturally during sleep and wakefulness and are core featur

🧠🧪 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:

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 ...

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?

The interplay between sleep and neural respiratory drive in COPD: contribution of semi-automated analysis of long duration recordings Neural respiratory drive (NRD) is a clinically relevant biomarker in patients with chronic obstructive pulmonary disease (COPD). However, its analysis…

🚨 New paper 🚨

And a new topic for me:
Brain 🧠 / breathing 🫁 interaction across wakefulness and sleep 💤 !
www.sciencedirect.com/science/arti...

We investigated how neural respiratory drive changes during sleep in patients with Chronic obstructive pulmonary disease (COPD).

👏 Congrats to Pierre Champetier (postdoc in the DreamTeam) for receiving this award in recognition of his work on the INSIGHT dataset, a longitudinal cohort of older adults with memory complaints 🧠
@institutducerveau.bsky.social

Huge effort from our group and many collaborators to create this dream EEG and mentation database! (published in Nat. Comm) 🌙💤

Huge congrats to our postdoc @champetier-pierre.bsky.social and his PhD lab for their great paper! 👨‍🦳🧘💤

🧠🧪💤 New preprint!

Sleep-like Slow Waves During Wakefulness Mediate Attention and Vigilance Difficulties in Adult ADHD

We show that intrusions of sleep-like activity during wake help explain attention lapses in ADHD.

📜 New preprint from @neuromorphicboki.bsky.social, postdoc working with @thomasandrillon.bsky.social. They used dynamical independence to examine changes in emergent dynamical structure in the anesthetized human brain!

Seeing the Mind, Educating the Brain

If you are in Paris on October 1-3 : we are organizing a fantastic cognitive neuroscience conference at Collège de France, on topics ranging from language to math, education and consciousness, with many of my favorite scientists !

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! 🥳

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)
