Mechanisms Of Working Memory Allocation In Reward Learning
Saturday, August 2nd, 1-2:15pm

#67 - @dbehrlich.bsky.social , Aspen Yoo, & Anne Collins. Investigating Working Memory Write And Clearance Operations During Reward Learning

#106 - Chiara Caldinelli, Jing-Jing Li, Garrett Chao, Mike Arcaro & Anne Collins. The role of the thalamus in dynamic decision-making

#27 - Jing-Jing Li, Connor Chen & Anne Collins. Humans integrate heuristics and Bayesian inference to efficiently explore under uncertainty

Looking forward to #RLDM2025! We have three posters tomorrow. Come chat with us!
#26 - Ti-Fen Pan; Gaia Molinaro ; Anne Collins - When 0 is good: instrumental learning with counterintuitive goals decreases working memory engagement

Humans use working memory to support RL, but how do we manage its content when faced with a stream of information? Check out our new preprint with @dbehrlich.bsky.social !

Out today: we discovered a new class of social hallucination - perception of chasing with high confidence. It is elevated in people who are paranoid and people who perceive meaning in the universe www.nature.com/articles/s44...

Important paper!

Im not sure the Discussion fully delineates its radical implications.

No more...

* Place cells
* Grid cells, splitter cells, border cells
* Mirror neurons
* Reward neurons
* Conflict cells

(continued)

Since no one did it, here is a list of people doing research on working memory. The list is admittedly biased (based on the people I follow), so please help: don't hesitate to let me know of someone missing. I will happily follow and add them to the list!

Please RT🙏

A thread...
Lab’s latest at PLOS Comp Biol, led by
@carrisacocuzza.bsky.social: “Distributed network flows generate localized category selectivity in human visual cortex”. This one changed how I think the brain works! Even "localized" functions are likely generated by distributed processes [1/N]

There are many nuances regarding the structural neural plasticity associated with antidepressant drugs. 💊🧠

We share our thoughts here in a Nature Reviews Neuroscience article, led by Clara Liao with co-authors from Conor Liston’s lab at Weill Cornell.

"the mediodorsal thalamus independently represents cueing and rule uncertainty. This enables the relevant thalamic population to drive prefrontal reconfiguration ... appropriately attributing errors to an environmental change."

Latest pre-print from the lab.

The notion that goals are central to human cognition is intuitive, yet learning and decision-making researchers have often overlooked the topic. In this Trends in Cognitive Sciences review, @annecollins.bsky.social and I propose it’s time to start studying goals in their own right 🧠 t.co/He6PIpQdt9

Albert Qu in Linda Wilbrecht's lab at UC Berkeley has posted a new preprint on striatal dopamine during learning:

The key takeaway is that a Bayesian reinforcement learning model provided a better match to the data compared to non-Bayesian alternatives.

Happy to post here for the first time and let the world know that we just published a new paper!

Please take a look if you are interested in context-dependent decision making, across-area interactions and low-rank RNN 👇
