No they don't! Humans report being conscious half of the time when awoken from NREM sleep.
The NREM/REM, conscious/unconscious dichotomy has been thoroughly debunked.
It's time we stop oversimplifying the relationship between sleep and consciousness!

What happens when the brain slips into a microsleep?
An example from a highly drowsy participant showing a brief loss of responsiveness (at time 0s). Details of the research: www.biorxiv.org/content/10.6...
Our scientifically accessible book chapter "Spontaneous Thoughts and Experiences across Wakefulness and Sleep" is now available. Wonderfully led by @parboulakis.bsky.social, w/ @jdsitt.bsky.social and @thomasandrillon.bsky.social. Edited by #LuciaMelloni and #UmbertoOlcese👇👇👇
New paper from our group: using simultaneous EEG-fMRI, we investigated the neural mechanisms underlying individual NREM sleep slow waves. Our findings suggest that slow waves are not a homogeneous phenomenon and may reflect distinct physiological processes.

In subjective cognitive decline, resting-state #sleep like slow waves predict:
1) amyloid and neurodegeneration status 🧠
2) memory performance 📝
3) conversion to amyloid positivity within 2 years

Following a microsleep, arousal-promoting subcortical nuclei come back online in a beautiful sequence, restoring wakefulness and responsiveness. This video captures such a recovery in a drowsy participant performing an attention task.

Using simultaneous EEG-fMRI, we identify two types of NREM slow waves with distinct thalamic profiles. Large, synchronized waves involve early thalamic activation and arousal markers, whereas smaller ...

Growing evidence supports a critical role of sleep slow waves (SW) in Alzheimer's disease (AD). However, wake SW (sleep-like SW potentially reflecting local intrusions of sleep) remain .....

I've had access to Claude 5 Fable for a bit. A genuine jump in capability, I could feed it a 15 page design document for a project and it would work for 9+ hours and deliver terrific results.
But working with it is weird & weirder is coming
Lots of examples: open.substack.com/pub/oneusefu...
Nature Human Behaviour, Published online: 27 May 2026; doi:10.1038/s41562-026-02446-zChowdhury et al. report the discovery of a 19–45-Hz thalamic oscillation that is present during human wakefulness and REM sleep, but not NREM sleep.
