It outputs results to a webpage [1], but I can't download it as a video. (It's for a talk)
I tried gifcap.dev to screen-record but you can't see the smooth flow on the network edges
*it's a SierpiΕski flow (PDE on a SierpiΕski lattice)

π₯You will see in general that brains, societies of humans, and AI are all networks, and the best synergies of all 3, or of 2 of them, involve networks with mutual feedback
π₯For example, AI is being improved by humans iteratively improving it, not just by backpropagation π

An intriguing interview [1] with my fellow Yorkshireman+inimitable brain mapper Dr Karl Friston on the free energy principle +social networks*
*you will often see a modular hierarchical organisation emerging in human consortia to rapidly communicate information via dual graphs as we noted in [2]

PAPER: apertureneuro.org/article/1450...
Looking forward to teaching our #USC neuroscience PhD students tomorrow, 32 years after starting as a nervous new student who knew 0 neuroscience :) Fortunately the main textbook now weighs 9 pounds - 3.5 times heavier than in 1993 !!
@USCNGP
π₯ DOES SCHIZOPHRENIA have SUBTYPES? What about other brain disorders?
π₯ Brilliant new paper www.nature.com/articles/s41... by @alisaffet.bsky.social +Cemre Candemir of the SoCaT lab (pictured) explains how 'biotypes' are defined, + why
π₯ Explained more in this VIDEO: www.youtube.com/watch?v=nPH-...
