🎉 📜 NEW #PREPRINT !! 📜 🎉
Spearheaded by Adam Barrett we tried to tackle some of the challenges of IIT.
We confront aspects worth delving into, with an incredible team of collaborators, inc. Pedro Mediano, @frosas.bsky.social, Daniel Bor, Lionel Barnett, and @anilseth.bsky.social.
If you need a method to infer causality from neural data, even when the signal is short, check our recent paper:

Schematic of theta waves and gamma packets recorded from the mouse visual cortex
How does the visual cortex coordinate neural activity over spatial and temporal scales? We found broad θ waves organize local γ bursts and spiking, forming a flexible spatiotemporal code to multiplex feedforward/feedback signals. Now out in full @natcomms.nature.com: doi.org/10.1038/s414... 🧵
I've been inspired to become a founder of a new startup that develops brain-to-brain interface technology. It's called Talk. We're going to reinvent communication for the digital age.
The best part is that we're able to zero-shot transfer the full computational stack already used by your brain!
Nine subcortical/cerebellar atlases included in the subcortex_visualization Python package (and subcortexVisualizationR package in R). The atlases are depicted in two-dimensional vector graphic format.
The extended version of my thesis procrastination project/subcortex visualization package is out now in both Python and R, now that I’ve graduated 🤠 This figure shows the 9 atlases included (and counting)!

Finally, after much delay from the BBC, Marnie Chesterton's "What Is Quantum?" is being broadcast at 9.30 am on Radio 4 on Tues 30th Dec. Recorded on Helgoland in the summer, with input from the leading figures in quantum mechanics (and me).

Really hoping bifurcations are the new manifolds. What a time to be alive 🥲
1/ "Hemispherotomy leads to persistent sleep-like slow waves in the isolated cortex of awake humans" - out now in @plosbiology.org, led by Michele Colombo, Jacopo Favaro, & Marcello Massimini. 🧠
This was a whole lot of fun. The paper is unapologetically nerdy (even by vision science standards), and it was also a dream come true to work with Hugh Wilson extending his model to a new domain.
The first paper in the series ⬇️

TLDR?
We derive a closed-form expression for the hysteretic difference between contrast thresholds for awareness and suppression, and test a prediction of the expression in human psychophysical data.

The final paper of my PhD is now out as a preprint. This is a follow-up piece in series of two companion papers modelling awareness and suppression in a new variant of continuous flash suppression.

What changes and what stays the same as you scale from single neurons up to local populations of neurons up to whole brains?
Michael and Mac @macshine.bsky.social on the systems approach to study brains across scales.

Thank you so much for having me!! I always have a blast chatting with @bethfisher.bsky.social and this time was no different! 💕 Also I loved your reflections in the end and how both of you have change your mind perhaps a bit through sharing your experiences with each other. So cool and precious!
The first major output of the @templetonworld.bsky.social @arc-intrepid.bsky.social adversarial collaboration testing IIT & predictive processing theories of consciousness is out now

Adaptive learning is coordinated across behaviour, time and neurobiology (from synapses and dendrites, to astrocytes and the systems level).

OHBM Oz rego + abstracts now open. Get amongst it!
I wrote a Comment on neurotheory, and now you can read it!
Some thoughts on where neurotheory has and has not taken root within the neuroscience community, how it has shaped those subfields, and where we theorists might look next for fresh adventures.

It’s touching and wonderful the amount of people saying reading Pratchett has made them a better person, myself included.
Was it @adamchapman.bsky.social I remembering saying that his downstream positive effect on UK society is something we should increasingly be considering as his readers age?
🎊Ain’t no party like a thesis submission party🎊
Honored to have submitted my PhD as a recipient of the Paulette Isabel Jones Career Development Award from The University of Sydney!
Thank you x1000000 to MVP supervisor @bendfulcher.bsky.social & co-supervisor @macshine.bsky.social 😊
I need some help from the #neuroskyence Bluesky-verse. Anyone know the source of this ~quote from Walter J. Freeman Jr.: "the secrets of the brain are hidden by two of God’s own firewalls: neurobiology and non-linear dynamics". I read it yrs ago but can't seem to find my way back to the source.
Position open for a neuroimaging focused postdoc to come work with us in Sydney
Feel free to get in touch for a chat if you have any questions about it :)

Interested in cortical wave dynamics? Check out our new preprint led by J Cruddas with @jchrispang.bsky.social where review the physics and physiology of cortical waves and their implications for psychological function:

@nsb-lab.bsky.social
New electron microscopy study in @nature.com Neuroscience finds that layer 5 ET neurons mostly connect to inhibitory cells locally, esp. those suppressing other excitatory cells, suggesting a "winner-take-all" system.

After five years of confused staring at Greek letters, it is my absolute pleasure to finally share our (with @smfleming.bsky.social) computational model of mental imagery and reality monitoring: Perceptual Reality Monitoring as Higher-Order inference on Sensory Precision ✨

moritz kriegleder presenting a slide on the current state of consciousness science
finally recovered from all the thought provoking discussions I had at @assc28.bsky.social! presented a meta analysis of the current state of consciousness science and why we should leave theory convergence behind (based on work with @mnoichl.bsky.social & @niccolonegro.bsky.social)
📜🪇[PUBLISHED]: NEW PREPRINT!🪇📜
I am incredibly excited to announce that we have published our paper on how "Dynamical independence reveals anaesthetic specific fragmentation of emergent structure in neural dynamics"

Strap in!
1/n
A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.
Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.
www.biorxiv.org/content/10.1...
New paper!
We introduce an efficient set of statistical features for fMRI time series (calibrated on mouse manipulation experiments and tested on mouse and human data): catchaMouse16.
Paper: doi.org/10.52294/001...
Code (python/Matlab/C): github.com/DynamicsAndN...
Pairs well with www.nature.com/articles/s41...
“Our results indicate that individual V1 neurons do not signal how the actual visual input deviates from the animal’s predictions, as postulated within the predictive coding framework”
Thrilling to see a major theory get tested!
1/3) This may be a very important paper, it suggests that there are no prediction error encoding neurons in sensory areas of cortex:
www.biorxiv.org/content/10.1...
I personally am a big fan of the idea that cortical regions (allo and neo) are doing sequence prediction.
But...
