See here for our paper: www.cell.com/current-biol.... It is a great pleasure to work on this model with Tianhao, Si Wu and @neilburgess10.bsky.social. Also, I highly recommend to first read the experimental paper by @azvollan.bsky.social and colleagues: www.nature.com/articles/s41...
A systems model of alternating theta sweeps via firing rate adaptation
Ji, Chu et al. present a network model of direction and grid cells, which generates
an internal direction signal comprised of alternating left-right sweeps of encoded
location and direction, based on ...

Amazing!🤩 Fascinating to see how completely different systems converge on left-right-alternation 🐜🐭🦇

Massive thanks to my supervisors @m-bmoser.bsky.social and @edvardmoser.bsky.social and coauthor @rjgardner.bsky.social for an incredible collaboration over many years! Thanks also to the technicians and lab members @kavlintnu.bsky.social and everyone else who contributed along the way (incl. 🐭!)

Similar to how bats use directed sonar beams to sample information from the external environment, we believe that sweeps may sample from the brain’s internal model of the environment to facilitate encoding/retrieval processes.
