Analysis of Receptor’s Distribution in Entorhinal Cortex after Induction of Spreading Depression in Juvenile Rats [PDF]

, 2015
Spreading depression (SD), discovered by Leao in 1944, is a pathophysiological wave which propagates slowly in the brain (3 mm/min) and cause dramatic ionic and hemodynamic changes.

Neuronal Plasticity in the Entorhinal Cortex

Neural Plasticity, 2008
The entorhinal cortex (EC) is a unique and fascinating structure, constituting a highly parallel interface between phylogenetically old cortex (hippocampus) and higher neocortical areas. The literature related to the EC has increased dramatically in the past 30 years. A simple PubMed search for EC lists around 20–40 articles per year in the early 1980s.

Depressive Symptom Dimensions and Their Association with Hippocampal and Entorhinal Cortex Volumes in Community Dwelling Older Adults

Frontiers in Aging Neuroscience, 2018
Objective: Research has shown that depression is a risk factor for Alzheimer’s disease (AD) and subsequent cognitive decline. This is compounded by evidence showing an association between depression and reduced hippocampal volumes; a primary structure ...

Mnemonic discrimination relates to perforant path integrity: An ultra-high resolution diffusion tensor imaging study. [PDF]

, 2016
Pattern separation describes the orthogonalization of similar inputs into unique, non-overlapping representations. This computational process is thought to serve memory by reducing interference and to be mediated by the dentate gyrus of the hippocampus ...

Entorhinal Cortex Thickness across the Human Lifespan [PDF]

Journal of Neuroimaging, 2015
ABSTRACTBACKGROUND AND PURPOSEHuman entorhinal cortex (ERC) connects the temporal neocortex with hippocampus and is essential for memory retrieval and navigation. Markedly, there have been only few quantitative MRI works on the ERC geometric measurements in pediatric and adult healthy subjects across the lifespan.

Temporal Lobe and Frontal-Subcortical Dissociations in Non-Demented Parkinson's Disease with Verbal Memory Impairment.

PLoS ONE, 2015
ObjectiveThe current investigation examined verbal memory in idiopathic non-dementia Parkinson's disease and the significance of the left entorhinal cortex and left entorhinal-retrosplenial region connections (via temporal cingulum) on memory impairment ...

Optimal Population Codes for Space: Grid Cells Outperform Place Cells [PDF]

, 2012
Rodents use two distinct neuronal coordinate systems to estimate their position: place fields in the hippocampus and grid fields in the entorhinal cortex.

Network Neurodegeneration in Alzheimer’s Disease via MRI based Shape Diffeomorphometry and High Field Atlasing

Frontiers in Bioengineering and Biotechnology, 2015
This paper examines MRI analysis of neurodegeneration in Alzheimer’s Disease (AD) in a network of structures within the medial temporal lobe using diffeomorphometry methods coupled with high-field atlasing in which the entorhinal cortex is partitioned ...

Change in background context disrupts performance on visual paired comparison following hippocampal damage [PDF]

, 2009
The medial temporal lobe plays a critical role in recognition memory but, within the medial temporal lobe, the precise neural structures underlying recognition memory remain equivocal. in this study, visual paired comparison (VPC) was used to investigate

The medial entorhinal cortex keeps Up

Nature Neuroscience, 2012
A study reveals that medial entorhinal cortex layer III spiking dynamics shape the neocortical-hippocampal dialog during Up-Down state fluctuations in slow-wave sleep that may contribute to memory consolidation.
