Ever wondered what happens in the brain when meditation becomes effortless? 🧠 In the first paper from my postdoc, we investigated the neurophenomenology of brain criticality — a state poised between order and disorder, thought to support flexible and efficient information processing 🧵 1/7

A landmark mechanistic study on the visual computational changes under psilocybin. I did my masters internship in Tomas's lab so it's wonderful to see such elegant computational psychedelic neuroscience. Congrats to Marco and co. 🧠🎉🍄

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!

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...

Interesting study - ketamine increases the complexity of brain activity (LZC) in patients with disorders of consciousness, but doesn't improve level of consciousness. Imo we need to be a bit more critical of the proposed statistical complexity <=> consciousness link. www.cell.com/iscience/ful...
cell.com
A Pilot Human Study Using Ketamine To Treat Disorders of Consciousness
Post-comatose disorders of consciousness (DoC) represent persistent neurological conditions with limited therapeutic options and a poor prognosis. Recent works advocate for exploring the effects of psychedelics to enhance brain complexity in DoC and ameliorate their consciousness. We investigated sub-anesthetic concentration of the atypical psychedelic ketamine for treating post-comatose prolonged DoC through a double-blind, placebo-controlled, cross-over trial involving three adult patients. Incremental concentrations of intravenous ketamine and saline were administered, alongside continuous EEG recording and assessments of conscious behaviors and spastic paresis.
