“…While the compression observed in the horizontal plane can be related to general effects in magnitude estimation such as the regression effect [ 32 ], the vertical stretching shows quite the opposite tendency. Questions arise as to how to interpret these results with respect to the anisotropy of a weaker performance of navigation in the vertical versus the horizontal dimension, which was described in rodents [ 4 , 7 ], dogs [ 12 ], and humans [ 13 ]. PET measurements in the latter study showed increased glucose metabolism in the right hippocampus, bilateral retrosplenial cortex, and pontine tegmentum during horizontal navigation [ 13 ].…”

“Taller and Shorter”: Human 3-D Spatial Memory Distorts Familiar Multilevel Buildings

Animal experiments report contradictory findings on the presence of a behavioural and neuronal anisotropy exhibited in vertical and horizontal capabilities of spatial orientation and navigation. We performed a pointing experiment in humans on the imagined 3-D direction of the location of various invisible goals that were distributed horizontally and vertically in a familiar multilevel hospital building. The 21 participants were employees who had worked for years in this building. The hypothesis was that comparison of the experimentally determined directions and the true directions would reveal systematic inaccuracy or dimensional anisotropy of the localizations. The study provides first evidence that the internal representation of a familiar multilevel building was distorted compared to the dimensions of the true building: vertically 215% taller and horizontally 51% shorter. This was not only demonstrated in the mathematical reconstruction of the mental model based on the analysis of the pointing experiments but also by the participants’ drawings of the front view and the ground plan of the building. Thus, in the mental model both planes were altered in different directions: compressed for the horizontal floor plane and stretched for the vertical column plane. This could be related to human anisotropic behavioural performance of horizontal and vertical navigation in such buildings.

“…Our current study on 3-D orientation and spatial memory in humans was stimulated by an accidental observation made in dogs living for several days with their owners in a multilevel hotel [ 12 ]. The dogs had difficulties finding the right floor but correctly ran to the corresponding “right door” on the “wrong floor”.…”

“…This improvement has been attributed to the increased cost associated with moving vertically: because moving vertically is much harder, animals are motivated to minimise the errors made in that dimension. This is supported by many experiments demonstrating that localisation of the horizontal coordinate of a goal is usually better than its vertical coordinate (Brandt and Dieterich 2013;Brandt et al 2015;Zwergal et al 2016). The exception to this are animals that can move in all dimensions with equal effort, such as fish (Holbrook and Burt de Perera 2013) and hummingbirds (Hurly et al 2010).…”

Volumetric spatial behaviour in rats reveals the anisotropic organisation of navigation

We investigated how access to the vertical dimension influences the natural exploratory and foraging behaviour of rats. Using high-accuracy three-dimensional tracking of position in two- and three-dimensional environments, we sought to determine (i) how rats navigated through the environments with respect to gravity, (ii) where rats chose to form their home bases in volumetric space, and (iii) how they navigated to and from these home bases. To evaluate how horizontal biases may affect these behaviours, we compared a 3D maze where animals preferred to move horizontally to a different 3D configuration where all axes were equally energetically costly to traverse. Additionally, we compared home base formation in two-dimensional arenas with and without walls to the three-dimensional climbing mazes. We report that many behaviours exhibited by rats in horizontal spaces naturally extend to fully volumetric ones, such as home base formation and foraging excursions. We also provide further evidence for the strong differentiation of the horizontal and vertical axes: rats showed a horizontal movement bias, they formed home bases mainly in the bottom layers of both mazes and they generally solved the vertical component of return trajectories before and faster than the horizontal component. We explain the bias towards horizontal movements in terms of energy conservation, while the locations of home bases are explained from an information gathering view as a method for correcting self-localisation.

“…However, this difference could have arisen from reduced attention to visual landmarks during vertical navigation. It has also been reported that dogs correctly remembered horizontal locations within a floor but not the vertical floor itself ( Brandt and Dieterich 2013 ). However, it is not clear whether the dogs’ navigation errors were due to inherent differences in vertical and horizontal encoding, or because of unequal landmark information consequent upon a lack of visual and odour controls in this study.…”

Humans commonly operate within 3D environments such as multifloor buildings and yet there is a surprising dearth of studies that have examined how these spaces are represented in the brain. Here, we had participants learn the locations of paintings within a virtual multilevel gallery building and then used behavioral tests and fMRI repetition suppression analyses to investigate how this 3D multicompartment space was represented, and whether there was a bias in encoding vertical and horizontal information. We found faster response times for within-room egocentric spatial judgments and behavioral priming effects of visiting the same room, providing evidence for a compartmentalized representation of space. At the neural level, we observed a hierarchical encoding of 3D spatial information, with left anterior hippocampus representing local information within a room, while retrosplenial cortex, parahippocampal cortex, and posterior hippocampus represented room information within the wider building. Of note, both our 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. These findings provide much-needed information about how the human brain supports spatial memory and navigation in buildings with numerous levels and rooms.
