When reading a line like "the glow of the flame briefly illuminated his face", most readers tend to build an image in their mind. 🧠 People with aphantasia, however, report that they do not. We wanted to know: Does this change how they physically read stories? (1/5)

are better-performing face recognition models more human-like? turns out: NO in terms of how we see/treat different faces as similar/different to each other, there seems to be tradeoff: better models are LESS human-like so they already work in some 'alien' ways... osf.io/preprints/ps... 🧠📈🧠🤖🧠💻

Numerosity adaptation suppresses monotonic neural responses to numerosity displays in the early visual cortex, with more suppression for higher numerosity adaptors. Therefore, numerosity adaptation effects begin in early sensory stages of processing. www.nature.com/articles/s42...

New preprint! 🚨→ Determinants of Visual Ambiguity Resolution. A new work with @ortiztudela.bsky.social @jvoeller.bsky.social @martinhebart.bsky.social and @gonzalezgarcia.bsky.social We created ~2k images and collected ~100k responses to study visual ambiguity. www.biorxiv.org/content/10.1...

Turns out, two of pain’s most famous messengers — Substance P and CGRPα — might not be so essential after all. Mice missing both still felt pain just fine, challenging decades of assumptions about how pain signals travel. buff.ly/ypISrtx

who says that science doesn't generate profit?

Very happy to announce that our paper “Sensory Horizons and the Functions of Conscious Vision” is now out as a target article in BBS!! @smfleming.bsky.social and I present a new theory of the evolution and functions of visual consciousness. Article here: doi.org/10.1017/S014.... A (long) thread 🧵

new preprint: osf.io/preprints/ps... aphantasics reported to feel less 'absorbed' as they read stories, but they dwelled just as much on words that typically evoke imagery. so perhaps they just didn't realize they have (non-conscious) imagery too Ali Moharramipour's 1st paper as senior author 🧠📈

i used to have blog on consciousness. i just uploaded my final post there, in which i responded to Alex Gomez-Marin & Anil Seth's recent commentary on the scientific status of IIT. inconsciousnesswetrust.blogspot.com/2025/03/fina... so long, folks. the world is going nuts. pls take care. 🧠📈

Remember the controversy about IIT last year - I have great sympathy to the critical side? Well if you want to think a bit about what pseudosciences are and whether we can distinguish science and paeudoscience here is a new short book ffeee download. t.co/6YvZ1kwLti

Now longer and in nature neuroscience. Why I (and 60+ of my closest friends) think IIT is pseudoscience. Has no empirical evidence. Has no hope of future empirical evidence. Open and closed case in my view.

New version of "the letter" in Nature Neuroscience. Like many others in the field, I signed because I believe that IIT threatens to deligitimize the scientific study of consciousness: www.nature.com/articles/s41....
