Reintroduction...
I'm a neuroscientist interested in emotion-motivation-cognition interactions.
Interested in conceptual/foundational issues.
I also wrote a book for general audience readers called The Entangled Brain that is open access at MIT Press.

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.

Are all PhD student inquiries now written almost the same way by AI??? I haven't look at applications yet, but probably the research statement too.
November 8, 2025 at 9:50 PM
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...)

Not to be publication police but the shift had seemed major 1-2 years ago.
Looking at the editorial board it seems to have serious scientists once more.
Curious about thoughts of the community.
