Now out in Hippocampus!! 📣💥 We examined anatomical inputs to the hippocampal region in six species - the tenrec, rat, marmoset, cat, macaque, and human - and found that hippocampal processing operates on fundamentally different types of information across species! (1/3) dx.doi.org/10.1002/hipo...

10/10 Massive thanks to everyone involved in this project @mschellenberger.bsky.social, @rjgardner.bsky.social, @m-bmoser.bsky.social, @edvardmoser.bsky.social, and many others @kavlintnu.bsky.social!
Show Post9/10 In summary, our results identify grid-cell-based sweeps as a flexible mechanism for rapidly querying any location in an animal’s immediate surroundings, and may support allocation of spatial attention within the cognitive map.
Show Post8/10 Based on the constellation of findings, we propose that sweeps function as an active sampling mechanism that reallocates spatial representation through parametric adjustments of sweep direction, alternation width, and frequency, similar to active sensing systems in other animals.
Show Post6/10 To determine whether this modulation extends beyond simple sensory tracking, we tested behaviors without external guiding stimuli. During backward locomotion (active or passive), sweeps reverse and align with movement direction:
