2D Virtual Reality-Based Exercise Improves Spatial Navigation in Institutionalized Non-robust Older Persons: A Preliminary Data Report of a Single-Blind, Randomized, and Controlled Study

Frontiers in Neurology, 2021
Background: Spatial navigation is a prodromal dementia marker. Exercise used alongside virtual reality improves many cognitive functions, but effects on spatial navigation are still unclear.Objective: To investigate the effect of virtual reality-based ...

Estimating water storage changes and sink terms in Volta Basin from satellite missions

Water Science and Engineering, 2014
The insufficiency of distributed in situ hydrological measurements is a major challenge for hydrological studies in many regions of the world. Satellite missions such as the Gravity Recovery and Climate Experiment (GRACE) and the Tropical Rainfall ...

Spatial Memory in Insect Navigation [PDF]

Current Biology, 2013
A wide variety of insects use spatial memories in behaviours like holding a position in air or flowing water, in returning to a place of safety, and in foraging. The Hymenoptera, in particular, have evolved life-histories requiring reliable spatial memories to support the task of provisioning their young.

Indoor Scene Intelligent Identification System Based on Spatial Topological Relationship Constraints [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Indoor scene identification can provide prior environmental information for indoor positioning applications, achieving positioning enhancement. Due to the similarity of wireless signals in adjacent spaces, it can lead to incorrect identification in ...

How does navigation system behavior influence human behavior?

Cognitive Research, 2019
Navigation systems are ubiquitous tools to assist wayfinders of the mobile information society with various navigational tasks. Whenever such systems assist with self-localization and path planning, they reduce human effort for navigating.

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.

The entorhinal spatial map integrates visual identity information of landmarks

Nature Communications
Landmarks guide navigation by providing information through their location and identity. The medial entorhinal cortex (MEC) is well known for representing landmark location, but whether it also encodes landmark identity remains unclear.
