Psychedelic 5-MeO-DMT induces dissociated state in mice A new study published in Communications Biology shows how an injection of the psychedelic compound 5-MeO-DMT induces a dissociated brain state in mice, combining elements of sleep and wakefulness.

A new "behind the paper" blogpost from @benbreant.bsky.social at @psl-univ.bsky.social on their recent publication dealing with the effects of the psychedelic 5-methoxy-N,N-dimethyltryptamine on mice brain:

Vigilance state dissociation induced by 5-MeO-DMT in mice - Communications Biology Administration of 5-MeO-DMT produces a dissociated brain state in mice, characterized by global slow-wave activity alongside behavioral wakefulness and marked pupil dilation.

Our paper with @vyazovskiy.bsky.social showcasing research conducted at @ox.ac.uk @oxforddpag.bsky.social is out!

We describe the effects of the psychedelic 5-MeO-DMT on brain states and sleep via EEG, LFP & freely moving oculometry.

I passed my DPhil viva yesterday 🎉 A huge thanks to my examiner, Stuart Peirson and Matt Jones who've done an exceptional job, and a bigger thanks to my Dphil supervisors Vlad Vyazovskiy, David Bannerman and Trevor Sharp!

Sleep-like state during wakefulness induced by psychedelic 5-MeO-DMT in mice Psychedelics lead to profound changes in subjective experience and behaviour, which are typically conceptualised in psychological terms rather than corresponding to an altered brain state or a distinc...

"Paradoxical wake" archive paper update, with new content & new prospects 🧪🧠
We show global slow waves after psychedelic administration + eye monitoring of freely-moving mice! A thrilling project with @vyazovskiy.bsky.social & @oxforddpag.bsky.social

Hey Nikolas! Can you add me as well? Thanks! 😄

How animals learned to hibernate and why we can’t do it (yet) | Aeon Essays Hibernation allows many animals to time-travel from difficult times to plenty. Could humans learn how to do it too?

An excellent read on hibernation from Vlad Vyazovskiy, and thoughts provoking as per usual!

“Paradoxical wakefulness” induced by psychedelic 5-methoxy-N,N-dimethyltryptamine in mice Vigilance states – waking, slow-wave sleep (SWS) and paradoxical sleep, are thought to be controlled by several cortical and subcortical neuromodulatory circuits, among which the serotonergic (5-HT) s...

Before working on dreams and human, I was studying psychedelic & sleep in rodents!
In this preprint from my DPhil thesis, we show the occurence of an altered state with features of both sleep and wake in mice injected with 5-MeO-DMT. Stay tune, there is more to come!
