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

Advanced 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 ...

Social influences on spatial memory [PDF]

Memory & Cognition, 2008
Three experiments were performed to examine the joint influences of spatial and social categories on memory for maps. Participants learned a map and descriptive information about small town businesses and, afterward, completed distance estimation and person-location matching tasks. Experiments 1 and 2 demonstrated that social (i.e., racial) and spatial

Transformation of spatial representations along hippocampal circuits

iScience
Summary: The hippocampus is thought to provide the brain with a cognitive map of the external world by processing various types of spatial information.

Impaired representation of geometric relationships in humans with damage to the hippocampal formation. [PDF]

PLoS ONE, 2011
The pivotal role of the hippocampus for spatial memory is well-established. However, while neurophysiological and imaging studies suggest a specialization of the hippocampus for viewpoint-independent or allocentric memory, results from human lesion ...

Sex-dependent effects of psychedelics: review of evidence from rodent models

Frontiers in Psychiatry
Classic psychedelics, including psilocybin, LSD, DMT, 5-MeO-DMT, mescaline, and phenethylamines such as DOI, exert their core effects through 5-HT2A receptor agonism, inducing widespread neurobiological and behavioral changes relevant to psychiatric ...

Molecular mechanisms for the destabilization and restabilization of reactivated spatial memory in the Morris water maze

Molecular Brain, 2011
Background Memory retrieval is not a passive process. Recent studies have shown that reactivated memory is destabilized and then restabilized through gene expression-dependent reconsolidation. Molecular studies on the regulation of memory stability after

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

The entorhinal spatial map integrates visual identity information of landmarks

Nature Communications
Landmarks guide navigation by providing information through their location and identity. The medial entorhinal cortex (MEC) is well known for representing landmark location, but whether it also encodes landmark identity remains unclear.

Search strategy analysis of Tg4-42 Alzheimer Mice in the Morris Water Maze reveals early spatial navigation deficits

Scientific Reports, 2022
Spatial disorientation is one of the earliest symptoms in Alzheimer’s disease and allocentric deficits can already be detected in the asymptomatic preclinical stages of the disease.

Billiards with Spatial Memory

Physical 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.
