A map of spatial navigation for neuroscience

Neuroscience and Biobehavioral Reviews, 2023
An animal's ability to navigate space is crucial to its survival. It is also cognitively demanding, and relatively easy to probe. For these reasons, spatial navigation has received a great deal of attention from neuroscientists, leading to the identification of key brain areas and the ongoing discovery of a ``zoo'' of cell types responding to different

Modified Navigation Instructions for Spatial Navigation Assistance Systems Lead to Incidental Spatial Learning [PDF]

Frontiers in Psychology, 2017
Spatial cognitive skills deteriorate with the increasing use of automated GPS navigation and a general decrease in the ability to orient in space might have further impact on independence, autonomy, and quality of life. In the present study we investigate whether modified navigation instructions support incidental spatial knowledge acquisition.

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.

Spatial navigation in young versus older adults

Frontiers in Aging Neuroscience, 2013
Older age is associated with changes in the brain, including the medial temporal lobe, which may result in mild spatial navigation deficits, especially in allocentric navigation.

Visual Navigation with Spatial Attention [PDF]

2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2021
This work focuses on object goal visual navigation, aiming at finding the location of an object from a given class, where in each step the agent is provided with an egocentric RGB image of the scene. We propose to learn the agent's policy using a reinforcement learning algorithm.

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 ...

A Multiple-Choice Maze-like Spatial Navigation Task for Humans Implemented in a Real-Space, Multipurpose Circular Arena

Applied Sciences, 2022
Spatial navigation is a key aspect of human behavior and it is still not completely understood. A number of experimental approaches exist, although most of the published data in the last decades have relied on virtual maze on-screen simulation or not ...

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
