Inductive learning spatial attention [PDF]

Sba: Controle & Automação Sociedade Brasileira de Automatica, 2008
This paper investigates the automatic induction of spatial attention from the visual observation of objects manipulated on a table top. In this work, space is represented in terms of a novel observer-object relative reference system, named Local ...

Probiotic supplementation prevents stress-impaired spatial learning and enhances the effects of environmental enrichment [PDF]

Frontiers in Microbiomes
Probiotics are live microorganisms that offer health benefits, influencing the microbiota-gut-brain axis. Probiotics can improve cognitive functions, including learning and memory, by modulating the gut microbiota, reducing inflammation, and producing ...

Comparing Immersive and Non-Immersive VR: Effects on Spatial Learning and Aesthetic Experience in Museum Settings [PDF]

Brain Sciences
Background/Objectives: The use of virtual reality (VR) solutions in design has rapidly increased globally. However, it remains unclear to what extent these technologies enhance people’s cognitive abilities.

Heliconius butterflies use wide-field landscape features, but not individual local landmarks, during spatial learning [PDF]

Royal Society Open Science
Spatial learning is vital in foraging ecology. Many hymenopteran insects are adept spatial foragers that rely on visual cues contained within broader wide-field scenes for central place foraging from a central nest.

Variable Selection and Allocation in Joint Models via Gradient Boosting Techniques

Mathematics, 2023
Modeling longitudinal data (e.g., biomarkers) and the risk for events separately leads to a loss of information and bias, even though the underlying processes are related to each other.

Representational integration and differentiation in the human hippocampus following goal-directed navigation

eLife, 2023
As we learn, dynamic memory processes build structured knowledge across our experiences. Such knowledge enables the formation of internal models of the world that we use to plan, make decisions, and act.

The effect of landmark visualization in mobile maps on brain activity during navigation: A virtual reality study

Frontiers in Virtual Reality, 2022
The frequent use of GPS-based navigation assistance is found to negatively affect spatial learning. Displaying landmarks effectively while providing wayfinding instructions on such services could facilitate spatial learning because landmarks help ...

Memantine and Riluzole Exacerbate, Rather Than Ameliorate Behavioral Deficits Induced by 8-OH-DPAT Sensitization in a Spatial Task

Biomolecules, 2021
Chronic sensitization to serotonin 1A and 7 receptors agonist 8-OH-DPAT induces compulsive checking and perseverative behavior. As such, it has been used to model obsessive-compulsive disorder (OCD)-like behavior in mice and rats.

Learned Spatial Data Partitioning

Proceedings of the Sixth International Workshop on Exploiting Artificial Intelligence Techniques for Data Management, 2023
Due to the significant increase in the size of spatial data, it is essential to use distributed parallel processing systems to efficiently analyze spatial data. In this paper, we first study learned spatial data partitioning, which effectively assigns groups of big spatial data to computers based on locations of data by using machine learning ...

Deletion of p75NTR rescues the synaptic but not the inflammatory status in the brain of a mouse model for Alzheimer’s disease

Frontiers in Molecular Neuroscience, 2023
IntroductionAlzheimer’s disease (AD), is characterized by a gradual cognitive decline associated with the accumulation of Amyloid beta (Aβ)-oligomers, progressive neuronal degeneration and chronic neuroinflammation.
