Very happy that our study looking at complex hallucination proneness across the lifspan is new out in Cortex! @GeorgiaMNeuro Laura Haye @mlisi6 @j_greenwood @thelablab @TesDekker sciencedirect.com/science/ar…

New preprint! With @GeorgiaMNeuro Laura Haye @mlisi6 @j_greenwood @thelablab @TesDekker biorxiv.org/content/10.1101/… We explored the tendency to experience complex hallucinatory imagery in older-age adults using experimental techniques (Ganzfeld/ganzflicker)
Reduced susceptibility to experimentally-induced complex visual hallucinations with age

Reduced susceptibility to experimentally-induced complex visual hallucinations with age

Visual hallucinations occur across many clinical conditions, but can also be induced experimentally in healthy individuals, using high-frequency flicker (Ganzflicker) and sensory deprivation (Ganzf...

We found that older adults reported fewer complex hallucinations both in real time and retrospectively, with none of our sensory or cognitive measures mediating this effect

We conclude that age-related changes (i.e. decreases in visual function) are insufficient to induce complex hallucinations & hallucinations in older adults may signal underlying pathology rather than being part of the normative ageing process

The brain decides if a movement belongs to you before you even make it. Fascinating @NatureComms study reveals that pre-movement alpha rhythms in motor cortex are not just preparatory, they’re the foundation of subjective control and sense of agency.

Benny Shanon, one of the pioneers of modern psychedelic research, has recently passed away. His book Antipodes of the Mind remains one of the most influential and beautiful books I have read. May his contributions carry forward in our work and explorations of consciousness

It is with great sadness that we announce the recent death of award-winning researcher and colleague Prof Eleanor Maguire. Prof. Maguire was a cognitive neuroscientist at @UCLIoN for more than 30 years. bit.ly/40fjpBk

Looking to recruit participants for an exciting (microdosing) psilocybin study I am running at UCL. Will involve two in person sessions. Please share and get in contact if you’d be interested in participating 🍄✨

We're still recruiting healthy participants for psilocybin study! If you have 3-5 lifetime psychedelic experiences, minimal meditation experience, and can commit to a 21-day prep course with visits to UCL over a 4-week period, we want to hear from you! psychedelicunit.com/dipp-pre…

So excited that our first 5-MeO-DMT paper is now available as a preprint!! 🧠🐸 This was (no doubt) the most meaningful project I’ve ever been a part of… … and @rhizoqualia is an absolute beast for sending it with this absolutely STUNNING analysis:

Ever wondered what happens in the brain when someone takes the world’s most powerful psychedelic drug?🧐Me too! So we went and found out. Our new preprint is now live where you can read all about it: biorxiv.org/content/10.1101/…

@oshenyan et al. demonstrate that hallucinations can be reliably induced in non-clinical samples using experimental techniques called Ganzfeld and Ganzflicker: nature.com/articles/s41598-0… 2/7

This Special Collection in @SciReports showcases the latest research on hallucinations and delusions, which can be symptoms of psychiatric illness, but are also part of a healthy range of experiences found throughout the general population: nature.com/collections/fejcd… 1/7

Hallucinations and delusions

This Collection highlights the mechanisms underpinning delusions and hallucinations and what we can infer from them about perception and psychiatric conditions.

I’ve asked Deputy Foreign Sec to summon the Iranian ambassador & demand #ToomajSalehi is released & Iran ends policy of using execution to stop political dissent. He was issued a death warrant for singing & making music. UK must stand up internationally for #humanrights @amnesty

Iranian authorities must quash Toomaj Salehi’s conviction and death sentence and release him immediately.
