I realized it's because I cared about how brains deal with layers of uncertainty by forming and updating many levels of expectations. And a good way to get uncertainty, along with the behavioral agency to address it, is letting animals behave freely in dynamic, uncontrolled environments.

There are many pitfalls and challenges. Nachum discusses this in the book, and one chapter is about technological developments that make it more feasible (this is also why @wheelerlab.org and I put some years into developing DIPLOMAT). But he also describes so many ways it has paid off

The back-and-forth between "control all variables" and "observe systems as they naturally occur" is probably as old as science. Nachum explains so many reasons, with so many elegant examples, why systems neuroscience needs a diversity and balance of approaches.

New preprint: There are some decent tools for multi-animal tracking, but it can still be difficult to track interacting animals without mixing them up. Isaac Robinson (with @wheelerlab.org and others) have developed a software solution that we are now using full time: doi.org/10.1101/2025...

How it works: instead of finding body parts within frames and then knitting these across frames, DIPLOMAT applies a hidden Markov model (Viterbi algorithm) that traces body parts through a video. We use the same movement and skeletal information as other tools, but as HMM transition probabilities.

I mentioned to a couple of people that I had a surprise waiting to be shared when Moderna got approval for its updated COVID-19 vaccine. It’s approved, and the big news??? Completely produced domestically!!!!! 🥳🤩 Approved as usual for all aged 6mo+!

New results for a new year! “Linking neural population formatting to function” describes our modern take on an old question: how can we understand the contribution of a brain area to behavior? www.biorxiv.org/content/10.1... 🧠👩🏻‍🔬🧪🧵 #neuroskyence 1/

biorxiv.orgLinking neural population formatting to functionAnimals capable of complex behaviors tend to have more distinct brain areas than simpler organisms, and artificial networks that perform many tasks tend to self-organize into modules (1-3). This sugge...

Authors should initially be in randomized order, with some "false authors" included. Then at the end of the paper we find out who the fake authors were ("I never would have guessed!") and who were the first and senior/corresponding authors ("wow, I thought he was dead").

Cool paper digging into circuitry of the median raphe

1. Imagine we land a space probe on one of Jupiters’ moons, take up a sample of material, and find it is full of organic molecules. How can we tell whether those molecules are just randomly assembled goo or the outcome of some evolutionary process taking place there? 🧪

Was at the hardware store today looking for special tape to seal air ducts. Really happy when, in the HVAC aisle, I found something called "duct tape". Took me several seconds before I realized what had just happened.

Many are convinced that drosophila have limited abstract thought. Here we show that by leaving corn flakes and a small piece of fruit in the sink stopper, flies develop a system of shared governance and, with time, enter a golden age of art and literature.
