At long last, I’m excited to share our latest preprint on the cortical topography of mental imagery! Building on the tethering hypothesis of brain evolution, we examined the spatial layout of imagery-driven neural activities to know how visual, auditory, tactile & multisensory imagery is organised.

I study how the brain processes language, mental imagery, and synaesthesia 🧠 I'm a lecturer at Birkbeck, University of London. More info in my website: https://roccochiou.weebly.com/ Our synaesthesia research: https://birkbeck-synaesthesia.weebly.com/
👁️🧠🧪 Vision takes time. But how does visual information flow through the human brain? Our new PLOS Computational Biology paper uses population receptive field (pRF) modelling to bring the spatial precision of fMRI to MEG, revealing the temporal dynamics of visual areas. 📖 doi.org/10.1371/jour...

And for our own contribution to the theme issue: Oliver Warrington and I show that the dentate gyrus encodes prediction errors during learning of perceptual predictions. This finding complements our previous work showing a transition from errors to predictions during learning (Aitken & Kok 2022). 🧠🟦
Dentate gyrus encodes prediction errors during learning of perceptual predictions
Abstract. The hippocampus is involved in learning predictive associations, responding to prediction errors as well as representing predictions of future in

The hippocampus sits at the interface of perception & memory, allowing us to link past, present, & future through its role in generating predictions. Excited to share this theme issue in @royalsociety.org's Philosophical Transactions B, co-edited with @barense.bsky.social & @mariamaly.bsky.social
An absolute banger of an exclusive from the Sunday Times. It's devastating. For the first time, I'm uncertain if Farage can actually survive this www.thetimes.com/uk/politics/...

What if much of human thought is navigation? 🧠 New open-access review: I argue that the DMN + hippocampal–entorhinal system form a domain-general engine for "mental navigation" across physical and abstract spaces (e.g. social, conceptual, and value). www.sciencedirect.com/science/arti...

🎉New paper out today in Nature Reviews Psychology🎉 with @mjdahl.bsky.social, @mariamaly.bsky.social, and @thiasmittner.bsky.social. We've been working on a unified framework for attentional states and the dynamics of transitions between them. 🧵
I love you, my students, who write genuinely awkward, human essays. That’s the whole point. We try.

I had not actively worked on synaesthesia research for more than 12 years. After moving from Sydney to the UK, my research over the past decade focused primarily on the brain basis of semantic cognition. It wasn't until joining Birkbeck last year that I decided to revisit synaesthesia tssues.
Professor Anina Rich was presenting her work on decoding the temporal profiles of synaesthetic versus real colours - how can we use MEG to assess different theories of synaesthesia? #synaesthesia @mqpsy.bsky.social #synesthesia
Professor Jamie Ward was presenting his work on #musicality and #synaesthesia 🎶🎵 🎶🎵 #IASAS2036 #Amsterdam #science
People with music-colour synaesthesia often see colours and shapes when they listen to music 🎶 #synaesthesia #synesthesia
Synaesthesia is not a disability, not a disorder, not abnormal. Adults, parents, teachers often dismiss their kids' synaesthetic experiences or believe they might be just "making up stories" or "seeking attention." We need to raise awareness & support kids with this unique condition. #synaesthesia
This is probably the most visually pleasing & aesthetically satisfying conference I've been to! 😃 #synaesthesia #IASAS2026 #Amsterdam #synesthesia
A small note for our reviewers: In the responses, we stated that revisions were in blue text. Following the journal's request, it's later changed to yellow highlighting, but we forgot to update blue to yellow in the response letter. Thank you for your suggestions, & please forgive this small slip 💝
n this project, generously funded by @leverhulme.ac.uk, we'll explore the cognitive and neural basis of the fascinating experiences of #synaesthesia! If you suspect you may have synaesthesia and want to get involved, visit surveymars.com/q/3O5k0Ax5H 🌈🧠🌞

I'm proud to say we are releasing LAION-fMRI, a densely sampled 7T fMRI dataset of natural images, with very broad stimulus sampling for testing countless hypotheses and for deeply exploring brain representations. The dataset is now available at laion-fmri.hebartlab.com What does LAION-fMRI offer? 🧵
LAION-fMRI - a 7T fMRI dataset of human vision
LAION-fMRI (LfMRI / LAION MRI dataset): 5 subjects, 25,052 launch-release natural images, 165 acquired 7T fMRI sessions with single-trial GLMsingle betas, retinotopy, localizers, and diffusion.

Re the council elections, I'm not surprised by the results but still feel disappointed. Good to see LibDem & Green have gained seats. The surge of Reform is expected but worrisome. I guess if Farage becomes the PM, his Home Secretary will curb the number of international students 😪Bad for all uni
Last year my book The Animal and the Thinker came out. Basic idea – how the operating principles of instinct and reason together answer big human questions. Right and wrong. Culture wars. Family and work. The meaning of life. That sort of thing. Now as an add-on I’m starting a blog…
I always assumed that brain function had to line up with cytoarchitectonics. It turns out I was wrong. Human cortex, especially PFC, is tiled by chains of functional patches that subdivide and interlink architectonic areas into parallel processing streams. www.biorxiv.org/content/10.6...
