Together, these results suggest that pure awareness is a distinct neurophenomenological state and demonstrate the unique value of combining large and rigorously matched cohorts with time-resolved phenomenology and systematic neural screening.

Finally, TM showed little evidence of carry-over effects from meditation into subsequent rest, in contrast to controls, where counting induced residual changes

In contrast, when TM was compared with its own baseline, low-frequency functional connectivity dominated, while temporal entropy contributed minimally to classification.

In relation to ordinary cognition in control subjects performing mental counting, pure awareness is best characterized by increased temporal entropy and scale-free neural dynamics.

Using EEG and multivariate classification analyses, our large-scale screening of theoretically motivated EEG markers revealed a double dissociation in neural signatures.

Using a well-powered study (33 meditators and matched controls), meditators demonstrated greater intensity and variability of pure awareness compared to controls, independent of practice duration, consistent with the notion of automaticity in achieving pure awareness during TM.

'Pure awareness' designates a mode of experience in which self-identification with the body or ego is dissolved, temporal orientation is suspended, and spatial reference frames are absent, while a distinctive quality of wakeful, alert presence is nonetheless preserved.

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! 👇

A big thank you again to Athena Demertzi and Emmanuel Stamatakis for organising a wonderful ASSC conference @assc28.bsky.social @theassc.bsky.social! See you all in Chile next year @assc2026.bsky.social !

My best ASSC so far at *ALL* levels. I had an absolute blast. Finding all possible "scientific" reasons to return to Crete asap 😇 @assc28.bsky.social #ASSC28.

Great talk, Vlada.

Happy to share the first project of my PhD at #ASSC28, on how voluntary strategies modulate the reading response and how this relates to suggestibility and metacognitive efficiency.

Appreciation to my collaborators, and to @fahrenfort.bsky.social for his support and supervision on this project.
