Phasic dopamine encodes persistent attraction to reward cues https://www.biorxiv.org/content/10.64898/2025.12.09.693300v1
very excited to share some of the final bits of work from my PhD! 🎉 we find that phasic DA in the accumbens simultaneously tracks persistent motivation towards reward cues in addition to new learning (but maybe not RPE?!) in sign-tracking rats. check out the preprint below!

Alex Pretti was a scientist.
Alex Pretti, the man shot by ICE in Minneapolis, appears to have previously worked with the federal government at the VA.
There is a photo of him on the VA website, where he’s cited as part of a medical research team.

Thousands of Minnesotans marched in downtown Minneapolis to protest ICE. The wind chill was 30 below during the march.
Hundreds of businesses closed their doors Friday in support of the protest as activists urged Minnesotans to abstain from economic activity.

New paper drop! 🧠💊 Our new paper out in Molecular Psychiatry shows that the serotonin 1B receptor is important for the neural and antidepressant/anxiolytic behavioral responses to psilocybin in mice.

Dorsolateral striatal acetylcholine reorganizes neural ensembles to anticipate threat
Adaptive behavior requires flexible encoding of emotional valence. Although striatal acetylcholine (ACh) signaling is critical for reinforcement learning, its contribution to aversive learning has rem...

Hemifield Specificity of Attention Response Functions during Multiple-Object Tracking
The difficulty of tracking multiple moving objects among identical distractors increases with the number of tracked targets. Previous research has shown that the number of targets tracked (i.e., load)...

despite the horrors, I will continue to share and engage with science without fear!! thus, I'm very happy to share my recent article out in Learning & Memory. I'm so proud of this work. it's been my little passion project for some time now. a student of mine, Angela Shang, even made the cover art!

Step 2) send an email or call their office
Step 3) tell them that federal spending on scientific advancement is the best hope we have to “win against china” or whatever these guys are obsessed with these days

if you are interested in behavioral microstructures of motivation, come check out my SfN poster today at board JJ8! we explore sign-tracking responses in depth, favoring detailed analysis of video behavior over automatic readouts (eg, presses per min). come check it out and talk behavior! ☺️
