New paper with @catehartley.bsky.social How does the reward structure of the environment influence the specificity with which children, adolescents, and adults learn and remember information? See preprint 🧵 and paper for our efforts to answer to this! #PsychSciSky www.nature.com/articles/s41...

Dorsomedial and ventromedial prefrontal cortex lesions differentially impact social influence and temporal discounting journals.plos.org/plosbiology/... new lab paper from the fantastic @zhilinsu.bsky.social with wonderful collaborators 🌟

The cortical insulation of addiction in the brain In the insular cortex, drug addiction would be represented by the creation of a new ‘need’ axis in population activity space that would be orthogonal to other more natural needs journals.physiology.org/doi/full/10....

Glucagon-like peptide-1 receptor agonists dramatically delay alcohol intoxication Since the speed with which a drug produces its effects influences its addictive liability, this mechanism may explain how GLP-1R agonists can reduce alcohol intake Insightful study 👏 www.medrxiv.org/content/10.1...

Excited to share our latest preprint looking at the neuroanatomical basis of impulsivity in youth! 🧠

⏰ Deadline Monday (28th) for @unibirmingham.bsky.social & @unileiden.bsky.social Computational Social Cognition summer school. Don't miss keynotes by Matthew Rushworth, @dianatamir.bsky.social & @davidamodio.bsky.social www.compsoccog.com ⬇️ Only text response questions in the short application:

Electroceuticals are expanding psychiatry’s toolbox | Doctors are turning to new tech for patients w/ #TreatmentResistantDepression & #OCD. Weighing in👉 @mountsinainyc.bsky.social neurologist Dr. Helen Mayberg & neurosurgeon Dr. Brian Kopell @washingtonpost.com www.washingtonpost.com/health/2025/...

When we use TMS to treat depression, we think it alters neural activity in a deep brain structure known as the subgenual anterior cingulate (sgACC). But this is hard to test directly, until our preprint with @coreykeller.bsky.social, @neuro-engineer.bsky.social, Nick Trapp, and Aaron Boes (UIowa) 1/

New preprint! We trained an RNN using RL to solve a decision making task used to characterize suboptimal decision making by Schizophrenic patients. First project exploring comp psych models, thanks to @adam-manoogian.bsky.social @shawnrhoadsphd.bsky.social @bqian.bsky.social @cpehlevan.bsky.social

We have multiple openings for basic addiction scientists interested in pursuing translational research within the Kahlert Institute for Addiction Medicine @kahlertumsom.bsky.social apply @ umb.taleo.net/careersectio... and learn about our institute @ addiction.umaryland.edu

getting this paper published was a bit painful but I am proud of it: www.nature.com/articles/s41.... We use deep RL to find mechanisms that help (real) people sustain the commons. Well done to Raphael Koster and Miruna Pislar (not on BlueSky). non-paywalled version on arxiv.

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

Interested in an update on connectomic and adaptive deep brain stimulation for obsessive compulsive disorder? Take a look at our summary of this exciting field and how things could be brought together out now in BPS: www.biologicalpsychiatryjournal.com/article/S000... A brief 🧵

Delighted our ( @jonroiser.bsky.social @profrobhoward.bsky.social) paper is now out in @brain1878.bsky.social ! 🎉🧠 We show that #Parkinson's #depression may stem from a reduction in reward sensitivity that is unresponsive to dopaminergic medication: 🔗 doi.org/10.1093/brai... 🧵⬇️

🚨 New paper 🚨 Out in @commspsychol.bsky.social: "Manipulating attention facilitates cooperation" with Claire Lugrin and @ccruff.bsky.social We use gaze data and display manipulations in one-shot Prisoner's Dilemma games and find that these manipulations can drive choices through attention 👇

Excited to have my PhD project paper exploring the network mechanisms of neuromodulation accepted for publication! We show how deep brain stimulation and medication exert a shared modulation of motor network synchrony in Parkinson's disease.

Excited to share the Saez lab’s latest work exploring the neural basis of human decision-making! Our new #JNeurosci study sheds light on local vs brain-wide activity underlying economic choices in the human brain. www.jneurosci.org/content/earl... (1/7)

Nature published a misguided op-ed on using LLM's in peer review. The author suggested LLM's could be an aid. But I was interested in a larger question. Can ChatGPT do a peer reivew? So I uploaded a first-submission manuscript for it to review. I also have human reviews for comparison.

Thrilled to share our new paper in PNAS on bargaining in the "wild" (eBay). We find that bargainers reveal private information by taking hours longer to reject good offers and accept bad offers. We can predict bargaining outcomes from response times. newsroom.ucla.edu/releases/res... 1/3

NIH cuts are getting the press, but VA research is getting slashed too. What do we lose when VA research goes away? Here's some greatest hits: The nicotine patch, invention of the cardiac pacemaker, first successful liver transplant, development of the CAT/CT scan prospect.org/health/2025-...

The link for this position had gone down for a bit; it's back up, and I am still looking for a postdoc excited to work with human intracranial data. Well-suited for animal electrophysiologists looking to jump to human data; all that's required is coding expertise and signal processing experience!

Effective therapy is so much more than saying the right words in the right order. Chatbots posing as therapists are dangerous. Some products "claim to have advanced degrees from specific universities, like Stanford" Glad the APA is speaking out about this. www.nytimes.com/2025/02/24/h...

An eternally long delay to drug reward In this work, we trained rats to report, so to speak, a subjective estimate of the delay of i.v. cocaine reward Their verdict: few tens of seconds, an eternity for rats which explains why cocaine is so low on their value ladder www.nature.com/articles/s41...
