  • We move along the surface of a doughnut. Whether the rat is exploring, running, dreaming, or resting deeply asleep, its brain's GPS constituted by the joint activity of grid cellls always move along the surface of a torus. By extracting and analyzing data from neural network of grid cells, researchers found that the collective neural activity is shaped like the surface of a doughnut. This is a first insight into how the mammalian brain structures high-level brain functions. Published on BioRxiv in 2021 by Kavli researchers (peer-reviewed version published in Nature 2022).

  • The raster plot shows several hundred mouse entorhinal cortex neurons oscillating at ultra-slow frequencies, spanning time windows ranging from tens of seconds to several minutes. As each cell oscillates, they also organise themselves into sequences in which cell A fires before cell B, cell B fires before cell C, and so on, until they have completed a full loop and return to cell A, where the cycle repeats.

  • Human participants navigated a virtual city on a fixed route along which they encountered objects. Pattern similarity analysis of the fMRI data showed that the similarity of object representations in the hippocampus reflected how far apart participants remembered these objects. The hippocampus represented both the distance in space in the city and time along the route.

  • Healthy volunteers learned the positions of buildings in a virtual city during training before undergoing an fMRI scan during which they imagined directions between these buildings. The entorhinal grid system was active during imagination of these directions.
