AI has come an enormous way since the early days...
Amazing precision and scholarly knowledge.
GoaLPleation for one is just around the corner in neuroscience research 😱

In a sense yes, but does network science help us understand the brain as a complex system? Intriguing paper.
If anything the paper has 800+ refs!

Hidden Markov Models
Speaking of HMMs, really enjoyed this paper on dynamics underlying resting state and other conditions. The idea of a baseline state from which excursions lead to more integrated states is really interesting.

Now that we have Hidden Markov Models do we still need correlation matrices?? 😀
For example, this looks cool.
(I'm aware that HMMs are not new, I played with them in grad school...)

Who says current AI is not great?
Excellent for solving Latex questions that would take me a long time to figure out myself (possibly never...). Easy to place a vertical line to highlight paper sections that need work 🤣
