New perspective paper from our lab: “The hippocampus as a generative model” out now !! royalsocietypublishing.org/rstb/article... The traditional view of the hippocampus is that it creates a cognitive map. Here we extend this view to conceptualise the hippocampus as a “generative model”.

The hippocampus as a generative model

Abstract. A generative model can be defined as a model of the latent causes of sensory input that can be used to generate new data samples. By examining em

PSA for trainees cold emailing with interest in joining a lab: Be careful about your use of LLMs in writing these emails!! It is now *extremely* common to get emails with a bizarrely-detailed, clearly-LLM take on a paper finding or with specific phrases pulled from the lab website. Don’t do this!

If you have (or will soon) complete your PhD & would like to join a thriving cultural evolution research group in NEW ZEALAND, drop me a line. UoA offers a handful of funded research fellowships. Applications must be made by a faculty member. Deadline August. Pls share with your students

After learning two equally structured graphs, an abstract relational map of their shared structure emerges in mPFC — but only after a few days 🧠 Huge thanks to all collaborators, especially @alonbaram.bsky.social for leading this and @behrenstimb.bsky.social for making so much of it possible.

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...

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

📣 New preprint 📣 "Neural Dynamics of Belief and Value Computations Guiding Strategic Social Decisions" We use EEG and computational modeling (combining learning + DDM) to explain participants' choices, RT, and neural signals in a strategic game. www.biorxiv.org/content/10.6...

Neural Dynamics of Belief and Value Computations Guiding Strategic Social Decisions

Successful strategic behavior must be grounded in beliefs about the opponent and her intentions. While many potential models have been proposed to explain choices in such situations, the neural mechanisms that govern learning and choice in complex strategic contexts remain poorly understood. Here, we use a computational model that combines dynamic learning and choice mechanisms to explain both choices and response times of human participants engaged in a competitive strategic task. Using electroencephalography (EEG), we identify temporally structured stages of neural processing that support an evolving value-based decision process, corresponding to first- and second-order belief updates and evidence accumulation related to the comparison of action values. Gamma-band phase coupling between central and parietal EEG signals varied with individual winning rate, suggesting that strategic behavior involves coordinated information transfer across spatially remote areas. Together, our data characterize the temporally evolving neural dynamics of belief and valuation processes that underlie strategic choice and provide neural validation for assumptions embedded in computational models of this behavior. ### Competing Interest Statement The authors have declared no competing interest.
