I am very thankful that my wonderful colleague Karen Bales (baleslab.bsky.social ) has signed on to direct our center moving forward. She's been a breath of fresh air and incredibly effective in the 2 years that she's been the interim in the role.

New preprint: visual attention may follow decisions more than it shapes them.
We identify behavioral signatures inconsistent with models in which attention affects value, instead pointing to a substantial post-decisional component.

Behavioral Signatures of Post-Decisional Attention in Preferential Choice
Attention plays a key role in decision-making by directing limited cognitive resources to relevant information. It has been proposed that attention also biases the decision process, due to a multiplic...

On NIH, rightwing thinktanks, and the future of science.
I wrote up something about the Mike Lauer IFP interview and what he seems to miss about science politics.

Science today is deeply tied up with democracy, politics, and the law. We must all work together. 🧪
Yesterday an interview was posted with Mike Lauer about the state of science. It's good in many ways, but there are some serious problems. I will write more later. But for now: I agree with Lauer...

For decades, imaging has forced the same trade-off:
Set a frame rate → sacrifice resolution or field of view to go fast.

We break that rule

Using an EVENT-BASED CAMERA, we record neural activity without frames. Signals are captured only where and when they occur:

Ultrafast Frame-Free Imaging of Neural Activity with Event Cameras
Frame-based fluorescence imaging has long defined how neural activity is optically measured. This approach requires acquiring all pixels within an image, regardless of whether they carry meaningful ne...

Even when they start dragging us away to the camps can we really blame those who don’t want to be next? So easy to sneer at the good Germans of 1940, not so easy to decide not to be one now.

New preprint. We show that in addition to reward prediction errors (RPEs), dorsal striatal dopamine signals encode sensory prediction errors (SPEs), the difference between sensory prior & observed stimulus. www.biorxiv.org/content/10.6...
Dorsal striatal dopamine integrates sensory and reward prediction errors to guide perceptual decisions
Perceptual decisions are shaped by expectations about sensory stimuli and rewards, learned through sensory and reward prediction errors. Dopamine is known to convey reward prediction errors that shape...

For 2026, I dare the human & rodent behavioral & cognitive neuroscience communities to find one NHP paper relevant to your research & cite it regularly next year when writing up your manuscripts. If you already cite one, find another one and double up. #Neuroskyence bsky.app/profile/vinc...
I definitely didn’t just scrape the web to get the h-index and total citation count as of 12/30/2025 for 319 living and dead nonhuman primate researchers to get a sense of publication metrics by rank on tenure-track.

Unfortunately this study, while heroic in many ways, does not take into account cardiac, respiration and other vasomotor effects, all of which have spatial signatures. Nor is there an electrophysiological measure of neural activity. Be careful before throwing the baby out with the bath water.
