That’s a wrap on #SfN2025 for our lab. Feeling grateful to do neuroscience with such an outstanding group — and to catch up with friends and colleagues across the community. SfN always reminds me how lucky we are to be part of this field.

Excited to share new work from our lab at #SfN2025! @sfn.org
Posters on how the brain learns about time and space—from foraging and MEC dynamics, to RNN + hippocampus in curriculum learning, to MTL vs striatal activity across learning, and cognitive aging in social isolation stress. Check them out!

Federal workers are speaking out on how the Trump regime is harming Americans:
"We stand here today at a moment of the greatest assault of our lifetimes on our freedoms. The US Constitution is being shredded... We are here to call on Congress to stand up and stop it."

How does the brain decide? 🧠
Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.
After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

Transitions in dynamical regime and neural mode during perceptual decisions - Nature
Simultaneous recordings were made of hundreds of neurons in the rat frontal cortex and striatum, showing that decision commitment involves a rapid, coordinated transition in dynamical regime and neura...

Congratulations to the Rising Stars in Neuroscience – Class of 2025! This is one of my favorite events each year, and this year was no exception.
Keep an eye on this incredible group of scientists—they’re doing amazing things!

Heading to #COSYNE2025?
Don't miss our latest work, led by Jack Bowler, on curriculum learning! We've uncovered how recurrent networks in the entorhinal cortex and RNNs develop specific dynamical mechanisms for abstract learning, depending on how they are trained.

Just spent 30 hours reviewing for an NIH study section set for Thursday—now postponed indefinitely. 20 other scientists did the same. This is happening across multiple sections. A huge waste of time, resources, and funding, with real costs for science and economy. Trump admin is bad for everyone.

Being a scientist in the U.S. feels especially stressful right now. Here’s a bit of early morning backcountry ski zen to share with you.

Federal judge extends restraining order on Trump administration's cap on NIH indirect costs
Judge Angel Kelley kept in place an order blocking the Trump administration from implementing a 15% cap on NIH indirect cost payments

NIH indirects case update:
Hearing ongoing now, and I'll try to live tweet some notable exchanges.
Prior to more detailed arguments, Judge Kelley starts off with a few point questions to both sides:
