More super important new science cautioning how we measure brain activity under the acute effects of psychedelics! Huge congrats to the authors!! πŸ§ πŸ©ΈπŸ„πŸ”¬

New preprint from collaboration with @sn-lab.bsky.social - 2p imaging of psilocybin's effects on neurovascular coupling πŸ§ πŸ”¬

We found that psilocybin prolongs the neurovascular response, independent of neural activity.

This would affect how we should interpret fMRI BOLD studies of psychedelics ‼️

Excited to share our latest work is up on bioRxiv! Looking at capillary flow speed changes we show that psilocybin prolongs the neurovascular coupling response to a visual stimulus. πŸ„πŸ”¬πŸ§ πŸ©Έ

Our paper on MouseGoggles - an open-source mini VR headset for mice - just came out! Really excited about finally integrating eye-tracking into the headset. Nice working with you @hongyuchang.bsky.social!
