While most animals live in a three-dimensional world, they move through it to different extents depending on their mode of locomotion: terrestrial animals move vertically less than do swimming and flying animals. As nearly everything we know about how animals learn and remember locations in space comes from two-dimensional experiments in the horizontal plane, here we determined whether the use of three-dimensional space by a terrestrial and a flying animal was correlated with memory for a…

Volumetric spatial behaviour in rats reveals the anisotropic organisation of navigation
TLDR
It is reported that many behaviours exhibited by rats in horizontal spaces naturally extend to fully volumetric ones, such as home base formation and foraging excursions, and further evidence for the strong differentiation of the horizontal and vertical axes is provided.
The Representation of Three-Dimensional Space in Fish
TLDR
Behavior experiments on pelagic fish are described, which suggest that fish, like mammals, have a higher order representation of space that assembles incoming sensory information into a neural unit that can be used to determine position and heading in three-dimensions.

Spatial learning in the cuttlefish Sepia officinalis: preference for vertical over horizontal information
TLDR
It is found that cuttlefish use vertical and horizontal spatial cues separately, and that they prefer vertical information to horizontal information, with priority given to vertical information.
Cue salience influences the use of height cues in reorientation in pigeons (Columba livia).
TLDR
This study investigated pigeons' use of wall height, a vertical cue, in an open-field task and compared it with their use of horizontal cues, suggesting that perceptual salience influences the relative weighting of cues.
Hippocampus, retrosplenial and parahippocampal cortices encode multi-compartment 3D space in a hierarchical manner
TLDR
Behavioural and neural findings showed that vertical and horizontal location information was similarly encoded, suggesting an isotropic representation of 3D space even in the context of a multi-compartment environment.

TLDR
Behavioral and neural findings showed that vertical and horizontal location information was similarly encoded, suggesting an isotropic representation of 3D space even in the context of a multicompartment environment.
Why study cognition in the wild (and how to test it)?
TLDR
It is thought that studying animal cognition in the wild is likely to be most productive when the questions addressed correspond to the species' ecology and when laboratory cognitive tests are appropriately adapted for use in the field.

Three-dimensional spatial representation in freely swimming fish
TLDR
Using an assay based on associative learning of the vertical and horizontal components of space within a rotating Y-maze, it is found that fish learned and remembered information from both horizontal and vertical axes when they were presented either separately or as an integrated three-dimensional unit.
Three-dimensional spatial cognition: information in the vertical dimension overrides information from the horizontal
TLDR
It is concluded that the cues that are present in the vertical axis of space (presumably hydrostatic pressure) override landmark cues that have been shown to be salient in experiments that only consider the horizontal component of space.

Representation of Three-Dimensional Space in the Hippocampus of Flying Bats
TLDR
Recorded single neurons in freely flying bats, using a wireless neural-telemetry system, and studied how hippocampal place cells encode 3D volumetric space during flight suggest that the bat hippocampus represents 3Dvolumed space by a uniform and nearly isotropic rate code.
Pigeon (Columba livia) encoding of a goal location: the relative importance of shape geometry and slope information.
TLDR
The present study explored how learning a geometry task is affected by training on a surface extending in the vertical dimension-a slope, and highlighted a potentially important role for slope as an allocentric cue for goal location.
