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 @Olitob123 @leechbrain @Joana_Cabral__ @ExpertPol
Check out this cool new paper by amazing @VinaoCarl !!
🚨 New paper out! 🚨
We uncover a universal dynamic routing architecture that governs how human cortical activity flows — conserved across individuals, brain states, frequency bands, and even in neurodegeneration.

Looking for a one stop high-dimensional time-series analysis platform for neuroimaging data? Dysco might be just what you are looking for!
Well done to @GAlteriis and @Olitob123 for seeing this one out!
DySCo is finally out in PLOS Computational Biology!
journals.plos.org/ploscompbi…… Check it out if you are interested in Functional Connectivity and spatiotemporal brain dynamics!
Thanks

"Duality" is a deep concept in mathematics, but an intuitive way to think about it is in terms of tables.
When we lay out data in a table, we are familiar with the idea that each row represents a different "entity", and each column represents a different "property". (1/10)

Excited to share our work on between-scanner test-retest reliability of ultra-low-field brain MRI morphometry and correspondence to high-field MRI: biorxiv.org/content/10.1101/… | We scanned 23 healthy adults (20-69 y) on two identical 64 mT @Hyperfine Swoop systems and 3 T MRI (1/n)
are you at #OHBM2024 ? Are you interested in Dynamic Functional Connectivity or tenuous links to 70s popular culture...? If yes: Please come and chat to either me or @Olitob123 and check out our poster (# 1545) tomorrow and on Thursday!
4/N The RMEVD algorithm can be orders of magnitude faster than naive approaches. Practically speaking, this means that DySCo allows to work with huge, non-parcellated dFC matrices, potentially real-time!
1/N dFC is a tool to understand how spatiotemporal interaction patterns change with time. In this toy example (3 signals), the brain switches from the blue to the green pattern. A single correlation/covariance matrix cannot capture this switch.

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. – at Lisbon, Portugal

Please check out our study on VIP interneurons & attention, now published in @NeuroCellPress.
Particularly proud that this first paper from the lab is essentially a negative result!

Led by the amazing @DMyersJoseph with @k47h4 @marianf_otero & @ClopathLab
Attention can enhance responses in sensory areas, and this is a pretty fundamental cognitive process, but how does this happen? Check out the latest preprint from our lab which tackles this question, led by the amazing Dylan Myers-Joseph! @DMyersJoseph biorxiv.org/content/10.1101/…
