Cortical connectivity, local dynamics and stability correlates of global conscious states - Communications Biology Time-resolved MEG modeling under Xenon anesthesia identifies posterior parietal connectivity and cortical stability as correlates of consciousness, with weaker parietal-occipital and parietal-to-prefrontal links marking reduced responsiveness.

Congrats to @ZhangChuyin ! This is our latest PREPRINT from our lab. While it originated as a reply to a critical paper, it ended up with a nice paper with philosophical claim on how to (and how not to) measure experience and new analysis methods of free-report based data!

After years of effort led by @qualiastructure.bsky.social (Nao Tsuchiya and William Wong), Jenny Windt, Katja Valli, Valdas Noreika and @rherzoga.bsky.social, the Dream database is now published in @natcomms.nature.com

**A dream EEG and mentation database**

only less than 7% of data marked as “available upon request” is actually accessible upon reasonable
request by researchers, according to a recent estimate

Dream start for database that aims to improve our understanding of conscious experience in sleep A research ‘dream team’ is collating a database to better understand how, when and why dreams occur.

Neuroimaging studies of dreaming are essential to investigate the neurocognitive processes of consciousness during sleep, but limited by the number of observations that can be collected per study. For press release See: www.monash.edu/news/article...

A research ‘dream team’ is collating a database to better understand how, when and why dreams occur. The paper co-authored by 53 authors across 37 institutes across the world explains how the DREAM database has evolved to coordinate existing research and encourage more.
