I use neuroimaging and neurostimulation to study how the brain processes language, semantic meaning, mental imagery, and synaesthesia πŸ§ πŸ³οΈβ€πŸŒˆπŸ³οΈβ€βš§οΈ I'm a lecturer at Birkbeck, University of London. More info in my website: https://roccochiou.weebly.com/

Totally agree.... i even feel Matlab is the most beautiful programming language, although i know Python people may beg to differ....

We show that synesthesia is sensory and automatic in nature: the pupil scales with the brightness of experienced synesthetic colors. doi.org/10.7554/eLif...
Now in its new dress @elife.bsky.social (convincing & valuable in round 1).
If anyone wants to pick up the method, happy to share & explain!

the human hippocampus receives convergent input from multiple sensory systems, yet we lack a basic understanding of how this structure integrates across senses.

we tackle this problem in our new preprint!

Our bilingualism paper is now published in PNAS. We used fMRI to compare semantic brain representations in English-Chinese bilinguals. Semantic representations are largely shared across languages, but finer-grained differences modulate how meaning is represented.

The AG is def involved in abstract semantics, and our data support this idea! But there's a catch - the ingredients of lexically mediate abstract meaning are likely stored elsewhere (possibly the STG) but the AG plays a crucial role in mediating online integration of conceptual pieces into a gestalt

Very grateful to have the opportunity to work with Beth Jefferies (not on Bluesky) and Francesca Branzi @fbranzi84.bsky.social on this project. πŸ˜ƒ

Any question on this work? Please let me know... 🌞

We found angular gyrus function can be best understood through a continuum from perception-guided to memory-guided cognition. As processing gradually becomes more perceptually decoupled and reliant on memory, the contribution of angualr gyrus increases! - more details in our paper (part 3 of 3) πŸ˜€

In this multimethod investigation, we integrated evidence from neurostimulation, neuroimaging, and experiential sampling to resolve this tension and provide more clarity regarding when and how the angular gyrus contributes to the semantic processing of concrete and abstract concepts! (part 2 of 3)

Our new preprint is now on bioRxiv: doi.org/10.64898/202...

There’s been a long-standing conflict about the role of angular gyrus in semantic processing: Why is it more active for concrete than abstract semantics? Does it play any role in abstract concepts despite its less activation?(part 1 of 3)

Official Statement From Valeria Chomsky Regarding Jeffrey Epstein As many are aware, my husband, Noam Chomsky, now 97, is confronting significant Β health challenges after suffering a devastating stroke in June 2023.

Noam Chomsky’s wife responds to the Epstein friendship. I’m a little disappointed the basic answer is just β€œwe didn’t do our research”. znetwork.org/znetarticle/...

Epstein’s economic power among academics was made possible by a capitalist system that makes higher education dependent on the charity economy rather than a public good supported by taxing the rich

This is especially true when studying the connectivity of the multiple-demand network and default-mode network, which show high level of contextual dependency, as compare to low level regions like the visual or sensorimotor cortex...

Important reminder that the relationship between functional connectivity and a trait is likely to be state-dependent, and hence it may be unwise to rely on resting state only

This seems to be based entirely on the Project Implicit sample, as reported in the un-refereed preprint linked from the NYT piece. Seems premature to declare this as fact in the NYT.

Opinion | What Are We Thinking?

Neuroscience is moving away from a modular view of the brain because the brain is not modular. It is network of murmuring neurons. Great metaphor by @pessoabrain.bsky.social

It won't actually exist for another month or so, but because it now 'exists' on amazon, I'll humbly observe that, after working through this book, your student/trainee would be able to read and understand all but two or three papers in this week's J. Neurosci. Check it out:
