Search Strategy Analysis of 5xFAD Alzheimer Mice in the Morris Water Maze Reveals Sex- and Age-Specific Spatial Navigation Deficits

open access: yesBiomedicines, 2023
Spatial disorientation and navigational impairments are not only some of the first memory deficits in Alzheimer’s disease, but are also very disease-specific. In rodents, the Morris Water Maze is used to investigate spatial navigation and memory.

Visual-spatial Working Memory Span of Indonesian Children with Deafness in Oral, Total, and Sign Language Communication Methods

open access: yesPsychological Research on Urban Society, 2020
Children with hearing impairment or deafness experience cognitive function delays but not limited visual-spatial working memory, which is commonly used to solve mathematical problems. Previous studies have discovered that visual or spatial working memory

Weak if any effect of estrogen on spatial memory in rats [PDF]

open access: yes, 2002
In a number of species, males appear to have spatial abilities that are superior to those of females. The favored explanation for this cognitive difference is hormonal: higher testosterone levels in males than in females.

Effects of HDAC inhibitors on spatial memory and memory extinction in SPS-induced PTSD rats

open access: yesResearch in Pharmaceutical Sciences, 2020
Background and purpose: Neurobiological changes in memory processes seem to play a role in the pathophysiology of post-traumatic stress disorder (PTSD). Memory itself is influenced by PTSD, too. Histone deacetylase inhibitors (HDAIs) have shown promising

A pathway for spatial memory encoding [PDF]

open access: yesLearning & Behavior, 2016
The medial prefrontal cortex has been shown to play a role for rodents in successful completion of tasks that require spatial memory, but the pathways responsible for the transmission of spatial information to the mPFC, and the nature and timing of such information, are unknown. Recently, Spellman, Rigotti, Ahmari, Fusi, Gogos, and Gordon (Nature, 522,

Human frontal eye fields and spatial priming of pop-out [PDF]

open access: yes, 2007
"Priming of pop-out" is a form of implicit memory that facilitates detection of a recently inspected search target. Repeated presentation of a target's features or its spatial position improves detection speed (feature/spatial priming).

Spatial memory in foraging games [PDF]

open access: yesCognition, 2016
Foraging and foraging-like processes are found in spatial navigation, memory, visual search, and many other search functions in human cognition and behavior. Foraging is commonly theorized using either random or correlated movements based on Lévy walks, or a series of decisions to remain or leave proximal areas known as "patches".

Complexity effects in visuo-spatial working memory: Implications for the role of long-term memory [PDF]

open access: yes, 2001
Author version made available in accordance with the publisher's policy.Several studies have shown that the capacity of visuo-spatial working memory is limited by complexity. Using a variant of the Corsi blocks task, this paper investigated the effect of

Electrical stimulation of prelymbic with different currents intensities on morphine induced spatial memory deficit in rats

open access: yesAdvanced Biomedical Research, 2016
Background: The medial prefrontal cortex (mPFC) is a part of brain reward system involved in cognitive functions such as learning and memory. Previous studies showed that electrical stimulation of prelymbic produced different effects on morphine-induced ...

Billiards with Spatial Memory

open access: yesPhysical Review Letters
Many classes of active matter develop spatial memory by encoding information in space, leading to complex pattern formation. It has been proposed that spatial memory can lead to more efficient navigation and collective behaviour in biological systems and influence the fate of synthetic systems.
