We collected ~4.7 hours of task data on 3 participants, listening to 10 different categories to create a functional gradient space in which we could situate category structure, and infer acoustic and semantic dimensions. Oh also, the data is open access! 👉 openneuro.org/datasets/ds0...

🧠🔊 New preprint! How does the brain organise natural sound categories? In our new fMRI study, we show that auditory cortex arranges sounds along continuous functional gradients, where acoustic and semantic structure are integrated into a shared representational space. doi.org/10.1101/2025...

Auditory Cortical Gradients Integrate Bottom-Up and Top-Down Structure During Natural Sound Categorisation
Understanding how the brain organises natural categories is a central challenge in neuroscience. While prior work has shown that categories can be decoded from distributed activity patterns in auditor...

We really need to start naming things in neuro stuff like "the sonic hedgehog pathway"

This looks great! Excellent work by @davidghaydock.bsky.social et al.

EEG microstate syntax analysis: A review of methodological challenges and advances

Our review provides a roadmap for researchers working on EEG microstate syntax. We hope to make results more comparable and useful for future studies, and call on researchers in the field to associate microstates to a continuous signal.

Beyond this, we point out that existing methods which try to associate EEG microstates with fMRI patterns make sweeping assumptions when using GLM models by averaging the EEG time series to single values per TR, heavily simplifying the EEG signal.

We argue that this common criticism can be investigated without throwing away microstate analysis by studying microstates in a continuous space (such as a t-SNE embedding, or similar). Note the information lost in the microstate representation!

A key issue highlighted (among others): is how microstate sequences are generated in and of themselves, in a “winner-takes-all” approach, where the complexity of the continuous EEG signal is simplified to a sequence of symbols.

David Haydock @davidghaydock.bsky.social · 21/02/2025
In our new review, we organise existing methods into clear categories and define how different studies construct microstates, define microstate sequences, and how they go about investigating a sequence once they have it.

David Haydock @davidghaydock.bsky.social · 21/02/2025
Studies on microstate syntax use a lot of different methods, and don’t always use the same process for defining the microstate sequence. Different terms are used for the same concepts, and documentation of the specifics of preprocessing and analysis steps can be lacking.

Ever heard of EEG microstates? Usually defined as cluster centres of topography, the dynamics of MS sequences are referred to as "syntaxes". Our new review discusses syntax methods and show how they could be better associated with the underlying EEG signal: 🧵👇 www.sciencedirect.com/science/arti...

Further than that actually - mind and world, perception and world, are just as inseparable.

David Haydock @davidghaydock.bsky.social · 26/12/2024
Our perception and the world aren't two separate things where one is guessing about the other - they're unified aspects of a single lived experience that co-emerge and define each other.

David Haydock @davidghaydock.bsky.social · 26/12/2024
No disrespect but saying that perception of the world is a brain-based best guess is like saying that a wave is the ocean's best guess about what water should do. Brain and world aren't separate things making predictions about each other - they're inseparable aspects of the same dynamic process.

If you'd have written an original piece on the matter and given inputs and opinions then there would have been a healthy discussion of the subject. Instead you've just created an argument about fair use and consent. Both of which you seem to be on the wrong side of.

David Haydock @davidghaydock.bsky.social · 15/12/2024
This isn't audience reaction, it's *author* reaction. That discrepancy is why you can't act as if use of LLMs is the same as writing an original piece. In any other context where you wrote about the paper, the contents of the paper is what would be discussed, which is what journalism should be for.

It's one thing to summarise it for yourself with a language model to get the gist of an article, but it's another thing entirely to re-present the article publicly using that summary.

David Haydock @davidghaydock.bsky.social · 15/12/2024
It makes more sense to me to identify the parts you'd want to run yourself. Relying on the summary of a language model instead of taking the time to absorb the source material inevitably means you will miss the finer detail. Like reading the abstract of a paper and thinking you understand the whole.

Picking a journal to publish our work sometimes felt like a headache. High fees and private, for-profit governance remain the (terrifying) norm. But this is changing: Aperture is a recent neuroimaging journal that is community-driven, low cost, and strives for high quality. See ⬇️

You need to put a watermark on these before someone nicks them and starts using them in TikTok's that have nothing to do with brain science

IMO the big breakthroughs won’t just come from advancing temporal and spatial resolution, but from achieving naturalistic recordings during dynamic, embodied interactions. Until we can move away from highly restrictive and overly reductive passive stimulation we won’t fully grasp mechanism.
