How can we design experiments that make computational models disagree? One section of our new @natrevneuro.nature.com Review with @kriegeskorte.bsky.social and @heikoschuett.bsky.social examines studies that used stimulus sets designed to elicit distinct predictions from competing models. 1/16

Now in Science: How does the brain’s navigation system allocate its limited representational resources during behavior? We found that grid cells sweep toward locations of interest, providing a potential mechanism for allocating spatial attention in the cognitive map.🧵 science.org/doi/10.1126/...

I would like to announce the Cutting Gardens EEG conference, a new global, decentralized, and sustainable way of organizing conferences. This conference is on EEG methodology and analysis pipelines, and it is comprised of different "gardens" around the globe, taking place from Chile to China.

Our work on goal-directed theta sweeps is out! We found two different types of theta sweeps in the rat hippocampus. During random foraging, left-right alternating sweeps dominated (Vollan, 25). However, during memory-guided navigation sweeps pointing to hidden goal locations emerged with learning.

Can humans actually learn sequential cross-modal statistical regularities? 🧐 Past research says "maybe not," but we think there’s more to the story. Our new paper investigates the confounding factors masking multisensory learning. psycnet.apa.org/fulltext/202...
