Check out this cool new study from the lab -- exploring the neural signatures of pure awareness experiences during Transcendental Meditation 🧠

Andres Canales-Johnson @canalesjohnson.bsky.social · 8d

Thrilled to share our new study: “Distilling the neurophenomenological signatures of pure awareness during Transcendental Meditation”, combining subjective reports with large-scale screening of neural features to investigate pure awareness. Thread below! 👇

It was a pleasure to present our findings at the Ernst Strungmann Institute in Frankfurt last week - on the psychedelic effects that breathwork can induce 🧠

A genuine joy to speak amongst heavyweights in the field of the neuroscience of altered states of consciousness!

Always a huge amount of work and thought that goes into these papers -- I'm excited to see what ecologically valid paradigms Micah and co. will develop next in the face of these surprising null results!

Micah G. Allen @micahgallen.com · Aug 27

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation

Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

I think until we start measuring interoception in the wild, close in time to symptoms, we are likely to keep finding this null association. We increasingly think of interoception more as a dynamic, psychophysiological state that is highly subject to contextual manipulation, rather than as a trait.

New preprint! 🧠

Our mind wanders at rest. By periodically probing ongoing thoughts during resting-state fMRI, we show these thoughts are reflected in brain network dynamics and contribute to pervasive links between functional brain architecture and everyday behavior (1/10).
doi.org/10.1101/2025...

Ongoing thoughts at rest reflect functional brain organization and behavior

Resting-state functional connectivity (rsFC)-brain connectivity observed when people rest with no external tasks-predicts individual differences in behavior. Yet, rest is not idle; it involves streams...

In partnership with metapsy.org we built an interactive dashboard for exploring the data. Users can:
• Filter studies by characteristics
• Test different analysis parameters
• Test moderators
• Download figures and reports

I have the pleasure of speaking at ESI-SyNC this year about the neurophenomenology of breathwork and DMT 🧠✨

Do come if you can!

Zero-Noise Lab @zeronoiselab.bsky.social · Jul 31

What shifts in our brain when our consciousness shifts? On Sept 8-9, we will explore this question at ESI-SyNC 2025 - with exciting talks, posters and discussions on the neural dynamics of altered consciousness, from psychedelics to breathwork, near-death experiences and meditation.

Unfortunately I can't make it, but there in academic spirit at @assc28.bsky.social.

If you're there, do check out our poster on the dose-dependent neurophenomenology of the psychedelic DMT 👇

@trisbek.bsky.social will be there to answer any q's 🧠

Hey Maria, thanks for this! I was actually at a workshop with Jeremy and Chris last week! Unfortunately they don't have any funding for postdocs at the moment, but they might do in the future, so will keep my eyes peeled. Funding databases are a good shout though - thanks!

I have strong data analysis and coding skills (MATLAB & python), project management skills, and love technical and non-technical writing (evan-lhealey.medium.com).

I would love to stay in the field of psychedelics, but am happy to look at a variety of options, in both academia and industry.

Yesterday I submitted my PhD thesis! 🥂

I'm now awaiting on the viva (17th June) to finalise everything, but am looking for job opportunities following this. If you could share this post far and wide, I'd really appreciate it.

Below is a (very) brief about me.

Our latest paper on DMT phenomenology, led by Pascal Michael, exploring the mis/matches with near-death experiences, showing that while 95% on DMT had at least one NDE feature, many classic NDE features were absent & only a very few had NDE-like trips in any way.

Our new paper - the first peer-reviewed brain and phenomenological examination of 5-MeO-DMT is out in Neuro of Consciousness.

TLDR: We tested whether ‘the mount Everest’ of psychedelics could induce a complete state of consciousness deconstruction while preserving awareness. 1/n

Hey Martha, not to worry - on reflection I would have thought that it might have been due to funny timings with our preprints. You can probably tell that I'm in frustrated thesis writing mode atm 😅 Glad to see it out after all this time and looking forward to seeing much more cool work from you :)
