Psilocybin, the active compound in magic mushrooms, alters perception and induces hallucinations. In this preprint, we show through visual illusions, fMRI and modeling that psilocybin affects contextual computations, a potentially general mechanism of psychedelics. www.biorxiv.org/content/10.1...

Thanks to everyone's feedback, we have updated our calculator to optimize sample size N & scan time T for fMRI studies: leonoqr.github.io/ORSP_Calcula... The first new feature is that users can explore how different N & T leads to different accuracy, e.g., N=1000 & T=30min => 81% max accuracy. 🧵

Human have higher sensitivity in the lower compared to upper visual field. It turns out that macaques show the opposite pattern: www.cell.com/current-biol.... I'd hypothesize that this is evidence that neither of these effects is innate; instead, they both develop with experience. #VisionScience

osf.io/preprints/ps... nice article, on why we may be totally wrong about aphantasia = imagery blindsight but i'm not sure i agree that for imagery representations to be perception-like, they need to be cross-decodable w/ normal perception. the brain can multiplex two sets of iconic signals 🧠📈

Jon Haidt told an Australian politician that scientists who disagree with him regarding social media harming kids are being shady & hiding evidence. This is bad because it misleads an influential policymaker about the strength of his evidence. But it gets worse… www.crikey.com.au/2024/12/12/a...

I'm curious to hear your impressions about "Mood". Unlike eg seeing and moving, it's purpose is less obvious - there are ideas but no one really knows. What do you think mood is for? Do you think of mood as a feature or a bug? (Why I'm interested - it's my new thing!) www.nicolerust.com/thepivot
