Extrahippocampal contributions to spatial navigation in humans: A review of the neuroimaging evidence

Hippocampus, 2021
Spatial navigation is a crucial everyday skill, which when impaired leads to a significant decrease in quality of life. In humans, functional magnetic resonance imaging (fMRI) has provided extensive insights into the neural underpinnings of navigation ...

The Influence of Polarimetric Parameters and an Object-Based Approach on Land Cover Classification in Coastal Wetlands

Remote Sensing, 2014
The purpose of this study was to examine how different polarimetric parameters and an object-based approach influence the classification results of various land use/land cover types using fully polarimetric ALOS PALSAR data over coastal wetlands in ...

Rethinking GPS navigation: creating cognitive maps through auditory clues

Scientific Reports, 2021
GPS navigation is commonplace in everyday life. While it has the capacity to make our lives easier, it is often used to automate functions that were once exclusively performed by our brain. Staying mentally active is key to healthy brain aging. Therefore,

Challenges for identifying the neural mechanisms that support spatial navigation: the impact of spatial scale. [PDF]

, 2014
Spatial navigation is a fascinating behavior that is essential for our everyday lives. It involves nearly all sensory systems, it requires numerous parallel computations, and it engages multiple memory systems.

Spatial Navigation and Visuospatial Strategies in Typical and Atypical Aging

Brain Science, 2021
Age-related spatial navigation decline is more pronounced in patients with mild cognitive impairment (MCI) and Alzheimer’s disease (AD) dementia. We used a realistic-looking virtual navigation test suite to analyze different aspects of visuospatial ...

Integrated GNSS Attitude Determination and Positioning for Direct Geo-Referencing

Sensors, 2014
Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers.

“CityQuest,” A Custom-Designed Serious Game, Enhances Spatial Memory Performance in Older Adults

Frontiers in Aging Neuroscience, 2022
Spatial cognition is known to decline with aging. However, little is known about whether training can reduce or eliminate age-related deficits in spatial memory.

Grid Cell Hexagonal Patterns Formed by Fast Self-Organized Learning within Entorhinal Cortex [PDF]

, 2009
Grid cells in the dorsal segment of the medial entorhinal cortex (dMEC) show remarkable hexagonal activity patterns, at multiple spatial scales, during spatial navigation. How these hexagonal patterns arise has excited intense interest. It has previously

Spatial frameworks in imagined navigation [PDF]

Psychonomic Bulletin & Review, 2006
The spatial framework model proposes that people use the extensions of their body axes as a reference frame for encoding spatial layouts in memory, and that the physical and functional properties of our bodies and the world determine the accessibility of egocentric locations from memory representations.
