Functional ultrasound imaging in freely behaving rodents gives new insights on the way brain regions adapt during repetitive tasks. Here see how hippocampus takes progressively the lead during rat locomotion in a corridor. @bergel_a et al in Nature Communications:rdcu.be/cbEoO

you are not a machine. you are more like a garden. you need different things on different days. a little sun today, a little less water tomorrow. you have fallow and fruitful seasons. it is not a design flaw. it is wiser than perpetual sameness. what does your garden need today?

Our new paper is out in Nature Chemical Biology where we describe our journey from a #covalent fragment screen to an in vivo active Pin1 inhibitor. nature.com/articles/s4158… Below is a musical abstract guest-starring Uri Alon and a tweetorial 1/n

"Thermodynamic Speed Limits for Multiple, Coevolving Subsystems" Follow this thread for highlights from today's seminar by Farita Tasnim (MIT Media Lab). Stream link: youtube.com/watch?v=ymkbQN… Abstract: santafe.edu/events/thermod…

"The speed limit of the evolution of a system is inversely related to the entropy produced." Real-world systems are constrained, path-dependent, modular, hierarchical. But Landauer's bound considers none of this... Farita Tasnim (MIT Media Lab) at SFI now: youtube.com/watch?v=ymkbQN…

~ "You're only as fast as your slowest components." i.e., "In the weeds, things move slower than they seem like they should from orbit." Farita Tasnim (MIT Media Lab) on deriving better speed limits for probability flows in nested modular systems: youtube.com/watch?v=ymkbQN… #entropy

"The numbers that you get for #entropy production depend on how much you coarse-grain the state space. If I measure my brain at the scale of the neurons versus at the fMRI, I'm going to get very different results." Farita Tasnim (MIT Media Lab) abyss-gazing: youtube.com/watch?v=ymkbQN…

🏅 Please RT: Applications are open for the SFI Complexity Postdoctoral Fellowships! We offer scholars unparalleled intellectual freedom & support for transdisciplinary research into the biggest questions facing science & society. Apply before 10/24/21: santafe.edu/news-center/ne…

A crucial part of my writing process is to include a blizzard of exclamation points and italicized words, then go back and remove almost all of them. In that first moment I need to let my enthusiasm shine through. Only later can I seem a bit more grown-up about everything.

Explore the science of intelligence with an intelligent scientist! SFI's Simon DeDeo (Laboratory for Social Minds) will teach four graduate seminars on the Future of #Intelligence November-Dec 2021. Open to the public, scholarships available-- details here: simondedeo.com/?p=931 Pls RT

“Neurophysiological evidence for cognitive map formation during sequence learning” - new preprint! biorxiv.org/content/10.110… This was a really fun project, exploring some interesting ideas about how the human brain supports learning abstract latent spaces (1/n)

Ecstatic to have started my stint as a visiting researcher at Santa Fe Institute, where I engage every day in deep thought about nonequilibrium statistical physics (to describe the emergent order in living systems) - with David Wolpert! This place is a research dream! Santa Fe Institute

Wonderful news! SFI Trustee Bill Miller just gave us the largest donation in the Institute's history — possibly the largest single contribution to complex systems research ever — which he calls "a bet on the future of humanity." 🥳 THANK YOU, BILL! 🎉 santafe.edu/news-center/ne…

Fascinating work now presented by Farita Tasnim at @APSMeetings shows how even simple models models of communication channels exhibit non-trivial thermodynamic properties. meetings.aps.org/Meeting/MAR22/…

When is noise good? When is slow better than fast? What are the limits to language, & to knowledge? This week on #ComplexityPodcast, Farita Tasnim (Massachusetts Institute of Technology (MIT)) & SFI Prof David Wolpert discuss their forthcoming research on the #Thermodynamics of Communication: complexity.simplecast.com/episodes/94

Very strong opening to a math video. Ok, you have my attention.
