How much of fMRI signals may be confounded by passive propagation over the structural network? Do canonical RSNs and FC gradients survive removing this confound? Check out our new preprint to find out!

Teabags shown to be a significant source of microplastics. They readily enter intestine cells in vitro and even interact with cell nuclei. I wonder what percent of my body is plastic… this cannot be good. www.sciencedirect.com/science/arti...

Teabag-derived micro/nanoplastics (true-to-life MNPLs) as a surrogate for real-life exposure scenarios
The potential health implications of environmental micro/nanoplastics (MNPLs) are increasingly concerning. Beyond environmental exposure, other source…

I find it intriguing that if 10 bits/s processing speed is accurate, and microstates are approximately 0.1 seconds, then could that suggest that each microstate represents approximately 1 bit of processing? #Neuroscience

Cool preprint by @misicbata.bsky.social I recall seeing an analysis like this done on social networks, so it's great to see it applied to the brain. It's getting me thinking about ways to also incorporate structural connectivity into this framework. #Neuroscience #Networks doi.org/10.1101/2024...

The brain selectively allocates energy to functional brain networks under cognitive control
Network energy has been conceptualized based on structural balance theory in the physics of complex networks. We utilized this framework to assess the energy of functional brain networks under cogniti...

There are things better left unknown, and mirror organisms seem like they could be one. Pros: maybe some health applications. Cons: Entire and irreversible ecosystem disruption. It's okay for humanity not to know everything!

Sometimes I think, "Compared to geological time, living things exist for only little blinks," but other times I think, "actually, life is one continuous chemical chain that first formed billions of years ago and every mountain range that existed back then has long since crumbled away to dust."

Visualizations from previous work with @rodlaje.bsky.social. The two output units in the top panel are driven by a chaotic RNN-and a small perturbation is injected at 0.16. In the lower panel the RNN is trained to "tame chaos"-creating a "dynamic attractor"-and a larger perturbation is injected.

Balancing integration and segregation is critical to brain function, and these attributes are often described by graph metrics. It turns out that structural connectome harmonics subsumes this framework by precisely extracting the integrative and segregative network features. #Neuroscience #Networks

Love seeing this idea gain traction. Brain harmonics provides a critical framework to continue exploring degeneracy in the brain.

Brain harmonics have Integrative, Segregative, and Degenerate regimes that have distinct properties. Degenerate harmonics have similar eigenvalues and contribute the most subject-specific network-level features. #Neuroscience #Networks #BrainFingerprinting Details in DOI: 10.1038/s42003-024-06669-6

White matter harmonics are wave functions describing brain signal distributions that live on the network. I presently believe that brain harmonics are critical to understanding what the brain does. #Neuroscience #ComputationalNeuroscience #NeuroPhysics
