Medial PFC interacts with the hippocampus to retrieve context-congruent memories.. but HOW?? was what started this. Simulating mPFC-HIP🧠, we designed an RNN🤖 that retrieves memories similar in context, on top of self-attention. It learns to retrieve like humans faster! arxiv.org/abs/2609.37791

Our task-switching paper is now out at Current Biology! www.cell.com/current-biol... We find that that our brains reset to a task-neutral state between trials, providing flexibility when the upcoming task is uncertain. RNNs also learn this strategy, but only when trained to switch tasks.

Sometimes we know an experience is important in the moment. Other times, its importance only becomes clear after the fact. Do these two cases have different consequences for memory? In our new paper we found that both kinds of prioritization impact memory in different ways! doi.org/10.1162/OPMI...

Excited to share my first-author paper now out in @natcomms.nature.com (www.nature.com/articles/s41...)! Here, we asked whether verbal narratives about social interactions activate the same brain areas as audiovisual presentations, and whether they overlap with theory of mind (ToM). (1/11)

Miao et al. find that recognizing social interactions in third-person narratives engages canonical brain areas subserving theory of mind. Using theory of mind recruits additional areas linked to action understanding.
