Building and Breaking the Chain: A Model of Reward Prediction Error Integration and Segmentation of Memory Abstract. Prediction errors drive reinforcement learning and organize episodic memory into distinct contexts, but do these effects interact? Here, we review the roles of midbrain dopamine, the locus c...

There are salient updates to attend to BUT if you’re wondering how they organize your memory, here’s a review/simulation offering diff. roles of prediction errors in building & breaking our models of the world w/ @davidclewett.bsky.social @jameswardantony.bsky.social inspired by Sarah DuBrow (1/7)

Complementary roles for hippocampus and anterior cingulate in composing continuous choice Naturalistic, goal directed behavior often requires continuous actions directed at dynamically changing goals. In this context, the closest analogue to choice is a strategic reweighting of multiple go...

Our "I would have seen it if it were there" paper — a collaboration with @ranimo.bsky.social and @clarepress.bsky.social — is now out in Psych. Review.

There’s a lot in this paper, but here are what I see as the 3 main takeaways:

How to communicate the value of curiosity-driven research The burden of proof is on us, as researchers, to explain why what we do is valuable to society.

Terrific how-to on communicating the value of basic research to the public in @thetransmitter.bsky.social by @tonyzador.bsky.social.

You may be curious. But when you are communicating the value of what you do, it’s not about you. Point to discoveries.

Fast-timescale hippocampal processes bridge between slowly unfurling neocortical states during memory search Prior behavioral work showed that event structure plays a key role in our ability to mentally search through memories of continuous naturalistic experience. We hypothesized that, neurally, this memory...

Super-psyched to share this preprint from my student Yicong (Alan) Zheng: "Recurrent Inhibitory Dynamics in the Entorhinal Cortex Support Pattern Separation" www.biorxiv.org/content/10.1... It's a new biologicaly-based computational model of the entorhinal-hippocampal system. Thread (1/?)

Don´t plot means & confidence intervals alone; your data is more than that! With easy raincloud plots in JASP you get the full picture and can draw better conclusions.
