As a field, do we think Prof Schultz’s own #dopamine neurons are spiking, dipping, or staying the same right now? 🖼️ 🧠 #SNE2026 @socforneuroecon.bsky.social
Prof Wolfram Schultz sitting in the audience at the 2026 Society for Neuroeconomics annual meeting seeing his famous figure of classic dopamine reward prediction error firing being presented during a talk. The figure is framed on the slide.  (posted with his permission)

#FluorescentFriday The lab’s 1st slice physiology recordings! Timelapse recording of striatal neurons ex vivo using a Thy1-GCaMP mouse 🐭 🧠 + glutamate in the bath. Thanks @neuromanonyc.bsky.social! Shout out to @keyenceusa.bsky.social who has been great to work with customizing the BZ-X800🔬

This speaks to the importance of cross-species research that is constantly forward- & back-translated between the clinic & lab. The importance of animal models leading to unanticipated discoveries - even in the realm of human psychology - is invaluable, especially in psychiatry🧠 tinyurl.com/yur3j2n8
From the linked press release: “Neuroscientists discover that a non-coding RNA molecule in the prefrontal cortex, which promotes resilience to depression only in women, alters how the female brain ruminates on the past when making certain types of decisions in a mouse model. The single-stranded RNA molecule LINC00473 is depicted in the center. Image generated by OpenAI.”

Here, we discovered LINC00473 in mPFC specifically altered change-of-mind decisions in female mice only. This was driven by enhanced sensitivity to sunk costs and how much re-evaluating recent mistakes influenced future choices. This is the 1st demo of non-coding RNA playing a role in cognition 5/6

A recent study led by @ornaissler.bsky.social found levels of the non-coding RNA LINC00473 were reduced specifically in mPFC 🧠 of women but not men diagnosed with MDD, based on post-mortem human 🧠 tissue studies. Expressing LINC00473 in mPFC promotes resilience to stress in female mice only. 4/6 🐭

Women are 2x as likely to develop depression than men. Major depressive disorder can manifest w different symptoms b/t sexes, including alterations in negative rumination on the past. Combining clinical questions, behavioral neuroscience, & translational #neuroeconomics, we dove into this deeper 3/6

We found striking sex differences in only change-of-mind choices, and not initial value-based judgements, in mice 🐭 working for food rewards of varying costs (delays ⏰) & preferences (flavors 🧀🍌🍫🍇) on our #neuroeconomic foraging task, Restaurant Row, while on a limited daily time budget. 2/6

From my graduate lab - single units in OFC & NAc as well as population decoding. Firing / representations of missed rewards into the next trial but only when encountering a worse offer on the next trial following an economic violation. Counterfactual / regret signals. www.nature.com/articles/nn....

Hi #ACNP2024 6th conference for me! I’m a physician-scientist Asst Prof in Psychiatry & Neuroscience studying decision-making across species. Come to our poster T185 on REGRET in humans. Huge collaboration across multiple labs - we want your help as a field to define this construct!🧠 #neuroeconomics
