Postdoc @ Neural dynamics of visual cognition (Cichy lab) @ FU_Berlin @freieuniversitaet.bsky.social interested in language🗣️📖 and its representations in the brain🧠 https://jiawei-liiiii.github.io/

Our postdoc Dr. Tianjiao Zhang has released "Its Complicated", a great software library that provides infrastructure to implement naturalistic, complex, interactive experiments in game engines. The toolbox supports peripherals and coding game logic for later analysis. gallantlab.org/Its-Complica...

Speech production is fast, complicated, cool (when the right thing is said...) Covert speech is a nice trick to study this. If you like speech planning, forward models, efference copies, brains this work is (we hope) helpful to clarify the brain mechs. #neuroskyence www.pnas.org/doi/10.1073/...

Temporally structured motor and auditory representations in covert syllable production | PNAS

Inner speaking—the deliberate generation of speech through covert production mechanisms—is a common human experience. Current accounts propose that...

Are brains and artificial neural networks converging onto universal representations? There is a seductive idea making the rounds in NeuroAI / machine learning: train systems well enough, and they all converge on the same representation of reality (i.e. a unique world model). We have thoughts™ 1/n

The Umwelt Representation Hypothesis: rethinking Universality

Recent studies reveal striking representational alignment between artificial neural networks (ANNs) and biological brains, leading to proposals that all sufficiently capable systems converge on univer...

How does a speech plan become fluent movement? In Nature Human Behaviour, led by Kumar Duraivel: Intracranial recordings reveal how hierarchical speech plans become continuous motor sequences across planning, articulation, and monitoring networks. doi.org/10.1038/s415... 1/5

Distinct neural processes link speech planning and execution - Nature Human Behaviour

Direct recordings from the human brain reveal a hierarchy in planning to speak, with neural activity organizing whole syllables before the individual sounds that compose them are sequenced.

Excited to share our new paper: "Probing the content of semantic representations in body-selective regions" We propose a framework based on object co-occurrence to interpret semantic representations of natural scenes predicted by LLM embeddings. doi.org/10.1162/IMAG...

Probing the content of semantic representations in body-selective regions

Abstract. Recent advances in neural networks trained on natural language have revealed that category-selective regions encode complex semantics and contextual information of natural scenes in addition...

We've posted a new fMRI study of semantic relations (has-part, is-a, made-of, etc.), a key aspect of language. We find that relations are represented in the same brain regions as are other semantic concepts, though voxels tend to be selective for only one relation or another. doi.org/10.64898/202...
