📣 Thrilled to share our recent work in @natneuro.nature.com. Using direct recordings from the human hippocampus and visual cortex, we asked how the brain prepares to encode information when upcoming events are unpredictable, and what ripples do in that process. www.nature.com/articles/s41...

How do we remember when an event occurred? In work with @virginievanw.bsky.social and @grassocamille.bsky.social we employed a novel virtual reality environment to present segmented sequences of images. The spatial structure of the environment had a dramatic effect on the remembering of 'when'.

An exciting MEG+pupillometry study by @quiringehmacher.bsky.social demonstrating coordination between mechanisms mediating perception and learning. Sensory cortex tracks prediction error continuously in a graded manner, while the brainstem only responds once crossing a threshold. Excellent summary👇
Quirin Gehmacher@quiringehmacher.bsky.social · 2mo agoNew preprint w/ @akalt.bsky.social, Juliane Schubert, Nathan Weisz, & @clarepress.bsky.social 🎉 Predictive-brain accounts treat "prediction error" as one signal. We find it's two jobs, in two dissociable systems. And one of them you can watch in the pupil, as people listen to a story. 🧵 (1/9)
