Development and validation of the Spatial Navigation and Memory Questionnaire (SPAM) [PDF]

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION Spatial navigation deficits may provide a sensitive and specific marker of early Alzheimer's disease pathology. However, few spatial navigation assessment tools are available for clinical practice that are accessible, time efficient, and ...

Spatial navigation – a unique window into physiological and pathological aging

Frontiers in Aging Neuroscience, 2012
Spatial navigation is a skill of determining and maintaining a trajectory from one place to another. Mild progressive decline of spatial navigation develops gradually during the course of physiological ageing.

Neural correlates of spatial navigation changes in mild cognitive impairment and Alzheimer’s disease

Frontiers in Behavioral Neuroscience, 2014
Although the memory impairment is a hallmark of Alzheimer’s disease (AD), AD has also been characterized by spatial disorientation, which is present from its early stages.

A synaptic signal for novelty processing in the hippocampus

Nature Communications, 2022
Memory formation and recall are complementary processes within the hippocampus. Here the authors demonstrate a synaptic signal of novelty in the hippocampus and provide a computational framework for how such a novelty-driven switch may enable flexible ...

Research on Remote GPS Common-View Precise Time Transfer Based on Different Ionosphere Disturbances

Sensors, 2020
Propagation path delays are a major error for the remote precise time transfer of common view; these path delays contain the ionosphere and troposphere impact, while the contributions of the ionosphere and the troposphere from common-view satellites to ...

Thermal Infrared Spectral Characteristics of Bunker Fuel Oil to Determine Oil-Film Thickness and API

Journal of Marine Science and Engineering, 2020
Remote sensing is an important method for monitoring marine oil-spill accidents. However, methods for measuring oil-film thickness remain insufficient. Due to the stable differences in the surface emissivity and temperature of oil and water, the oil film

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 ...

Multisensory input modulates memory-guided spatial navigation in humans

Communications Biology, 2023
Efficient navigation is supported by a cognitive map of space. The hippocampus plays a key role for this map by linking multimodal sensory information with spatial memory representations.

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,
