Humans and animals use mental representations of the spatial structure of the world to
navigate. The classical view is that these representations take the form of Euclidean …

Neural computations are often compared to instrument-measured distance or duration, and
such relationships are interpreted by a human observer. However, neural circuits do not …

INTRODUCTION Electrode arrays based on complementary metal-oxide semiconductor
silicon fabrication technology, such as Neuropixels probes, have enabled recordings of …

We describe an integrative model that encodes associations between related concepts in
the human hippocampal formation, constituting the skeleton of episodic memories. The …

To solve the spatial problems of mapping, localization and navigation, the mammalian
lineage has developed striking spatial representations. One important spatial representation …

As animals navigate on a two-dimensional surface, neurons in the medial entorhinal cortex
(MEC) known as grid cells are activated when the animal passes through multiple locations …

The retrosplenial cortex is reciprocally connected with multiple structures implicated in
spatial cognition, and damage to the region itself produces numerous spatial impairments …

Grid cells with their rigid hexagonal firing fields are thought to provide an invariant metric to
the hippocampal cognitive map, yet environmental geometrical features have recently been …

To guide navigation, the nervous system integrates multisensory self-motion and landmark
information. We dissected how these inputs generate spatial representations by recording …

The symmetric, lattice-like spatial pattern of grid-cell activity is thought to provide a neuronal
global metric for space. This view is compatible with grid cells recorded in empty boxes but …
