Ben Snow Sipes @itsbendetermined.bsky.social · 14/01/2026How 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! 010

Ben Snow Sipes @itsbendetermined.bsky.social · 19/12/2024I 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 010

Ben Snow Sipes @itsbendetermined.bsky.social · 13/12/2024Cool 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...doi.orgThe brain selectively allocates energy to functional brain networks under cognitive controlNetwork energy has been conceptualized based on structural balance theory in the physics of complex networks.

Ben Snow Sipes @itsbendetermined.bsky.social · 12/12/2024There 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! 120

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. 3659

Ben Snow Sipes @itsbendetermined.bsky.social · 22/11/2024Balancing 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 020
Ben Snow Sipes @itsbendetermined.bsky.social · 22/11/2024Love seeing this idea gain traction. Brain harmonics provides a critical framework to continue exploring degeneracy in the brain. 030
Ben Snow Sipes @itsbendetermined.bsky.social · 21/11/2024Brain 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/s42003-024-06669-6 070
Ben Snow Sipes @itsbendetermined.bsky.social · 20/11/2024White 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 1160
