Ed Kravitz passed away yesterday.
He was a remarkable scientist and mentor- brilliant, curious, creative, and kind. I am grateful to have learned from him. His legacy will endure through his science and through the many people he inspired.

We will miss you, Ed.

The New York Times piece today about US science is terrible and wrong—in many ways.

I could write a whole article about this, but as one example:

“To close observers, the original crisis began well before any of this…”
No. I’m a close observer of science, and this is incorrect.

My new essay for @thetransmitter.bsky.social. Why is understanding emotion so challenging? The debates around what counts as an "emotion" shed insight.

These disputes are multidimensional, principled and fascinating. Here, I unpack them.

Emotion research has a communication conundrum

In 2025, the words we use to describe emotions matter, but their definitions are controversial. Here, I unpack the different positions in this space and the rationales behind them—and I invite 13…

Everything everywhere all at once: Decision-making signals engage entire brain

The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.

Instead of just overriding satiety, this pathway commands a consummatory mode—mice eat pellets, lick air, whatever’s available—suppressing food-seeking in favor of ingestion. We think this is likely mediated by inhibition in the supratrigeminal region and disinhibition of orofacial motor neurons.

We set out to test how central amygdala inhibitory neurons gate satiation/satiety signals in the pons.
