Delayed, Reduced and Redundant: Information Processing of Prediction Errors during Human Sleep During sleep, the human brain transitions to a ‘sentinel processing mode’, enabling the continued processing of environmental stimuli despite the absence of consciousness. We employed advanced informa...

An absolutely precision-oriented read from the wider team of @canalesjohnson.bsky.social and co. on the information processing of prediction errors--an already high feat. They go further, relating it to environmental stimuli across sleep stages.

Academics vying for a spot in Epstein‘s world. There are so many. I feel the need to make a thread, so I don’t keep confusing them. 1/

I'm enjoying this piece so much!

Happy to share our new and groundbreaking study on the relationship between conscious awareness and the sense of bodily self! With @brainself.bsky.social at @ki.se and out today in PNAS: www.pnas.org/doi/10.1073/...

Why our physical bodies may be a core part of conscious experience – new research The brain’s sense of “this is my body” is tightly bound to conscious awareness – far more than many theories assume.

So happy our latest study is finally published!

We show that falls are a major issue across the lifespan for individuals with DCD (i.e., Dyspraxia).

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! 👇
