Firing rate adaptation in grid cells produces macroscopic hexadirectional modulation

The paper investigates the neuronal origin of hexadirectional modulation in grid cells using data from foraging rats, finding that firing rate adaptation explains the phenomenon.

Locomotion-dependent use of geometric and body cues in humans mapping 3D space

This study shows that human locomotion mode affects spatial memory precision and cue usage in 3D environments, with flying and walking groups showing opposite patterns in vertical and horizontal accuracy.

Adaptive cognitive maps for curved surfaces in the 3D world

This study investigates how humans represent curved surfaces in 3D space, finding that spatial representations are flexible and influenced by behavioral experience and task demands.

Encoding of 3D head direction information in the human brain

This study investigates how the human brain encodes 3D head direction information using a virtual 3D environment and fMRI, finding distinct roles for the thalamus, subiculum, and retrosplenial cortex in encoding horizontal and vertical directions.

Can we study 3D grid codes non-invasively in the human brain? Methodological considerations and fMRI findings

The paper develops software and an fMRI analysis method to test 3D grid models in humans, finding evidence for a face-centred cubic lattice model in entorhinal cortex.

Verbal paired associates and the hippocampus: The role of scenes

This study investigates why the hippocampus is involved in verbal paired associates tasks by comparing scene, object, and abstract word pairs using fMRI.

Hippocampus, retrosplenial and parahippocampal cortices encode multi-compartment 3D space in a hierarchical manner

The paper investigates how the human brain encodes 3D multi-compartment space, finding hierarchical neural representations and isotropic encoding of vertical and horizontal information.
