Really chuffed about this one. It's impt for our efforts to understand neural and computational bases of controlling the contents of WM. It also highlights a control-related signal in the beta band that is NOT "inhibitory" in the way often assumed doi.org/10.1523/JNEU...

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
