you want to extract instantaneous phase of a signal, the textbooks say to narrowband filter before computing the analytic signal. but why? using a broadband signal, the resulting phase corresponds to the circular mean of the analytic signals of the constituents (here: 🔴=🟢+🔵).

I'm delighted with the positive feedback I received from my talk! The stars are aligning for new brain theories to flourish! #NoosaBrain2024

Inspiring day at Michael Breakspear's Systems Neuroscience Lab with Michael Breakspear Alex Fornito Thomas Yeo Todd Constable (find me here @toddc.bsky.social) Lucina Uddin Daniel Margulies Fran Hancock 🇮🇪 🇵🇭 🇨🇭 and Mark Woolrich.

Visiting my copatriot Prof Marta Garrido, Director of the Cognitive Neuroscience Hub at Melbourne Uni, where I was welcomed by a very engaged audience! Also developing a mechanistic project with Borjan (Boki) Milinković. Still not sure how the brain works, but we're on it! 😅

Happy to share my latest insights into the origin of brain networks with the Brain Research Institute at UCLA! And proud to be listed alongside @ar0mcintosh :)

4/4 The damped oscillations reveal vibration modes, where the antiphase (red-blue) coupling ensures the convervation of energy. b - This high-order model illustrates how the collective system in spacetime (n,t) is the sum of modes defined in space (n) and oscillating in time (t).

Just finished one more figure to illustrate the Leading Eigenvector Dynamics Algorithm (LEiDA), for our upcomming toolbox paper. There's a lot of persistence behind each plot.

Here is DySCo, a general framework for dynamic Functional Connectivity! tinyurl.com/mu2v952x We unify multiple dFC approaches, their associated measures, and introduce an ultrafast algorithm to compute them! Thanks Oli Sherwood Rob Leech Joana Cabral Paul Expert

2/N There are multiple ways to compute time-varying interaction patterns (i.e. matrices): from simple correlation/covariance to approaches based on phase alignment. DySCo puts all of them together, with a unique set of tools and algorithms, given their common structure.

4 days left to submit your abstract for the 17th Brain Modes conference in Bilbao, Spain, 18-21 November 2024 brainmodes-bilbao-2024.eu Some abstracts will be selected for oral presentation, the others as posters! #BrainModesBilbao Hope to see you there!

Abstract submission extended until September 6! You're still on time to present your research at the 17th Brain Modes conference in Bilbao, Spain, 18-21 November 2024 brainmodes-bilbao-2024.eu #BrainModesBilbao Co-Organized with Jesus Cortes and Wael El-Deredy

Guys, if you're interested in neuroscience, consciousness, vibes, and groundbreaking science you've GOTTA watch this presentation. Dr. Joana Cabral provides shockingly strongly empirical evidence for the connectome-specific harmonic wave paradigm (cf. geometric eigenmodes). This
