Exactly @gershbrain.bsky.social! But more importantly: these mice are overtrained on this one task. Maybe stuff gets more broadly distributed across the brain if it is the one thing you do all day every day. And, they are MICE with tiny brains! So, important study, but let's not over-generalize.
Sam Gershman@gershbrain.bsky.social · 2w agoThis is a really interesting and important study: www.nature.com/articles/s41... However, isn't it concerning that sweeping conclusions about functional organization of cortex are being reached on the basis of a single task?

How does the human brain extract abstract structure from experience? We show that sensory-independent relational representations emerge in mPFC over several days. Work with @mgarvert.bsky.social and @behrenstimb.bsky.social now out in @currentbiology.bsky.social: www.cell.com/current-biol...
This looks solid!
Liz Siefert@lizsiefert.bsky.social · last mo.New preprint! We show low arousal states promote hippocampal ripple genesis in sleep and wake. This bridges rodent work, where ripples predominate during sleep, with human studies reporting ripples during active behavior, identifying low arousal as a common mechanism www.biorxiv.org/content/10.6...
When utilized in literature review, LLMs consistently 1. fail to mention female authors in female-led literatures, 2. insist that men are more influential or more heavily cited when this is contradicted by objective citation counts, and 3. attribute women’s work to hallucinated male scholars.
How do brains plan actions towards goals? To get at this question we studied mice navigating complex mazes as goals changed on every trial 🧵 Work with @thomasakam.bsky.social @behrenstimb.bsky.social @kristorpjensen.bsky.social now on BioRxiv: www.biorxiv.org/content/10.6...

🚨Paper alert!🚨 Across 5 expts, @mileritayar.bsky.social's new JEPG paper shows that people explicitly avoid switching between attention control states. Using demand selection tasks, we find that people don't just avoid cognitive conflict, but also switching between congruent and incongruent trials.
