Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]

, 2016
How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

Spatial navigation and multiscale representation by hippocampal place cells [PDF]

, 2011
Hippocampal lesions are known to impair success in navigation tasks. While such tasks could be solved by memorizing complete paths from a starting location to the goal, animals still perform successfully when placed in a novel starting position.

Easy rider: monkeys learn to drive a wheelchair to navigate through a complex maze. [PDF]

PLoS ONE, 2014
The neurological bases of spatial navigation are mainly investigated in rodents and seldom in primates. The few studies led on spatial navigation in both human and non-human primates are performed in virtual, not in real environments.

Virtual reality in neurologic rehabilitation of spatial disorientation

Journal of NeuroEngineering and Rehabilitation, 2013
Background Topographical disorientation (TD) is a severe and persistent impairment of spatial orientation and navigation in familiar as well as new environments and a common consequence of brain damage.

Successful wayfinding in age: A scoping review on spatial navigation training in healthy older adults

Frontiers in Psychology, 2022
IntroductionSpatial navigation is a complex cognitive function that declines in older age. Finding one’s way around in familiar and new environments is crucial to live and function independently.

Navigation of brain networks [PDF]

, 2018
Understanding the mechanisms of neural communication in large-scale brain networks remains a major goal in neuroscience. We investigated whether navigation is a parsimonious routing model for connectomics. Navigating a network involves progressing to the

Dynamics on Spatial Networks and the Effect of Distance Coarse Graining [PDF]

, 2010
Very recently, a kind of spatial network constructed with power-law distance distribution and total energy constriction is proposed. Moreover, it has been pointed out that such spatial networks have the optimal exponents $\delta$ in the power-law ...

Transformation of spatial representations along hippocampal circuits

iScience
Summary: The hippocampus is thought to provide the brain with a cognitive map of the external world by processing various types of spatial information.

Electrophysiological Signatures of Spatial Boundaries in the Human Subiculum. [PDF]

, 2018
Environmental boundaries play a crucial role in spatial navigation and memory across a wide range of distantly related species. In rodents, boundary representations have been identified at the single-cell level in the subiculum and entorhinal cortex of ...

Spatial Knowledge Acquisition for Pedestrian Navigation: A Comparative Study between Smartphones and AR Glasses

Information, 2023
Smartphone map-based pedestrian navigation is known to have a negative effect on the long-term acquisition of spatial knowledge and memorisation of landmarks.
