random neuroimaging question: does anyone in bluesky-land have access to the loadings for neurosynth topics in schaefer 400 (yeo7) space? #neuroskyence @misicbata.bsky.social @richardfbetzel.bsky.social @borismontreal.bsky.social @sofievalk.bsky.social

Can a virus help uncover Turing patterns in nature? In this @commsbio.nature.com paper, researchers show how the tulip breaking virus triggers the expression of a pigment that can display a broad range of (observable) stripe patterns @philipcball.bsky.social

🎊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 😊

This is what happens to successful authors. Caveat emptor.

Something similar happened (on much smaller scale) w/ one of my books. Amazon did nothing. Then a journalist reported on it. Amazon took down offending title.

I hope someone will report on this happening (much more blatantly) to Eric!

FRAUD ALERT: I have nothing to do with these phony books using my name on the cover. I have not written a memoir or partnered/inspired any cookbooks!
Attempts to get Amazon to take these down have gone nowhere.

Preprint⭐
Our attention changes over time and differs across contexts—which is reflected in the brain🧠 Fitting a dynamical systems model to fMRI data, we find that the geometry of neural dynamics along the attractor landscape reflects such changes in attention!

Geometry of neural dynamics along the cortical attractor landscape reflects changes in attention
The brain is a complex dynamical system whose activity reflects changes in internal states, such as attention. While prior work has shown that large-scale brain activity reflects attention, the mechan...

I've been thinking a lot about the preprint in terms of my own career. I grew up academically in computational labs. My papers were abstract early on and they only got more abstract as I progressed. The model was: find a new exciting mathematical tool. Apply it to brain imaging data. Write it up. 1/

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:

and: "but somehow power and control over vital issues – what is peer review, what is a journal, what gets published – have been ceded to organizations beyond the scientific community, like Web of Science and Scopus. This is not healthy for science or the scientific community."

I wrote to the president of Harvard. I hope other faculty will speak their conscience, even if it means more struggle ahead.

If you enjoy eschewing the need for parametric assumptions about the nature of a map’s SA as much as I do, check this one out!
Good spatial nulls are very important in neuroscience, and for assessing spatiotemporal patterns in many other physical systems 👇

How far can you compress a complex system?

🚨 In our latest paper we collapse high-dim compartmental models (from epidemics to ecosystems) into a single 1-D equation using quantum-inspired math, exposing universal phase transitions #ComplexSystems ‪👇👇👇
