Congrats Volker (@reisnerv.bsky.social). Collab with Doellerlab, modeling by Viktor Studenyak via the Neural Computation Group
Volker Reisner@reisnerv.bsky.social · last yr.New preprint! We explored how learned movement patterns affect our sense of traveled distance and proposed a neurocomputational model that leverages embodied memories to denoise spatial codes. 🔗 www.biorxiv.org/cgi/content/...

Re-enacting steps supports human path integration consistent with motor-corrected grid cell drift
Efficient navigation, especially in the absence of vision, requires path integration - the continuous updating of spatial position from self-motion cues. However, path integration is prone to cumulati...

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans. doi.org/10.1038/s414... With @doellerlab.bsky.social, Patrick Haggard, @vigano.bsky.social, Daniel Reznik
Curious about spatial memory in 3D? Our new preprint explores how environmental boundaries and the way we move affect our memory for locations in volumetric space! Huge congrats to co-1st @theoschaefer.bsky.social w/ Leonard König, Misun Kim, Christian Doeller. 🔗 www.biorxiv.org/content/10.1...
Locomotion-dependent use of geometric and body cues in humans mapping 3D space
The ability to represent locations across multiple dimensions of space is a core function of cognitive maps. While the influence of boundary-dependent environmental geometry on spatial representations...

🚨 New lab paper!🚨 A dream study of mine for nearly 20 yrs not possible until now thanks to NIH 🧠 funding & 1st-author lead @seeber.bsky.social We tracked hippocampal activity as people walked memory-guided paths & imagined them again. Did brain patterns reappear?🧵👇 www.nature.com/articles/s41...

The time course and organization of hippocampal replay
The mechanisms by which the brain replays neural activity sequences remain unknown. Recording from large ensembles of hippocampal place cells in freely behaving rats, we observed that replay content i...

Left–right-alternating theta sweeps in entorhinal–hippocampal maps of space - Nature
A study in rats proposes a mechanism for how the brain maps the surrounding environment, including places it has never seen, by alternating left and right forward sweeps in successive theta cycles.
