👉 We suggest that the brain's tendency to enter a hyperconnected-hyperarousal pattern under psilocybin represents the potential to entertain variant mental associations. For the first time, these findings link brain dynamics with phenomenological alterations, providing new insights into the neurophenomenology and neurophysiology of the psychedelic state.

💡 Changes in the neurobiological patterns displayed that psilocybin induced widespread increases in averaged functional connectivity.
💡Time-varying connectivity analysis unveiled a recurrent hyperconnected pattern characterized by low BOLD signal amplitude, suggesting heightened cortical arousal.
💡In terms of #neurophenomenology, canonical correlation analysis primarily linked the transition probabilities of the hyperconnected pattern with oceanic boundlessness (OBN), and with visionary restruct

🔧 Healthy participants received either psilocybin (n=22) or placebo (n=27) while in ultra-high field 7T MRI scanning. Changes in the phenomenological patterns were quantified using the 5-Dimensional Altered States of Consciousness (5D-ASC) Rating Scale, revealing alterations across all dimensions under psilocybin.

I know the world is crazy at the moment, but I'll preserve the likeness of creativity and share this latest work.

🍄 We know that psychedelics alter brain dynamics and subjective experience.
🧐 But how are these changes related?

Here, #HakwanLau gives lot of context for the "pseudo" word of rthe open letter. It's illuminating, I wish I read this earlier. Although not convinced by the P of the theory, I worry about the systemic flaws & salut the courage to safeguard the scientific stance of the C study

“A Student’s Guide to Open Science” walks students through the history of the replication crisis & the behaviours that we can engage in to improve transparency, replication, & reproducibility. It’s written for students, researchers, & supervisors. What’s behind the cover?
