- Reposted by Sofie Valkwww.pnas.org/doi/10.1073/... Awesome new work from Nick Weaver and Chris Lynn. How complicated is the human brain, really? This paper introduces a way to measure the compressibility of brain activity -- i.e. how many correlations do you actually need to predict large-scale neural activity. 1/
- Reposted by Sofie ValkVery happy to see this out now in @nathumbehav.nature.com - kudos to @magdadelrio.bsky.social who has led this work and nicely brought together data from two very different studies! article is here: doi.org/10.1038/s415... and PDF is here: rdcu.be/eZ27x
- New preprint from my postdoc with @tobiasuhauser.bsky.social at the MPC! TL;DR: there is a strong recency bias in information gathering and it is attenuated in people on the #OCD spectrum - a possible mechanism for #indecisiveness 🤔 Paper here: www.biorxiv.org/content/10.1... Thread below...
- Happy to have been able to contribute to this great work 👶🗻⛰️🏔️
- Very happy to see this great study by @skrohn.bsky.social @carstenfinke.bsky.social @engra.me @sofievalk.bsky.social on brain shape & human brain development, out in @natneuro.nature.com 🧪🧠 www.nature.com/articles/s41...

- Hello! It has been a while, but for the Hector Fellow Academy I created a small project at the interface of neuroscience and music. In short, it is like a neuro-jukebox of projects of friends and colleagues integrating music and art. I thought it would be nice to share here cng-lab.github.io/kiosk

- Very cool 🆒
- Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

- Reposted by Sofie ValkFun piece from @rossandersen.bsky.social about the "Hubble tension"--the problem that different methods for measuring the expansion of the universe give apparently incompatible results, which is leading some researchers to believe that something is drastically wrong with standard cosmological ideas.

- Reposted by Sofie ValkWhen I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...
