Effects of entorhinal cortex lesions on memory in different tasks

Brazilian Journal of Medical and Biological Research, 1997
Lesions of the entorhinal cortex produce retrograde memory impairment in both animals and humans. Here we report the effects of bilateral entorhinal cortex lesions caused by the stereotaxic infusion of N-methyl-D-aspartate (NMDA) in rats at two different

Medial temporal pathways for contextual learning: Network c- mapping in rats with or without perirhinal cortex lesions

Brain and Neuroscience Advances, 2017
Background: In the rat brain, context information is thought to engage network interactions between the postrhinal cortex, medial entorhinal cortex, and the hippocampus.

Left entorhinal cortex and object recognition [PDF]

NeuroReport, 2018
The present research explored the role of the medial temporal lobes in object memory in the unique patient MR, who has a selective lesion to her left lateral entorhinal cortex. Two experiments explored recognition memory for object identity and object location in MR and matched controls.

Heterosynaptic plasticity of the visuo-auditory projection requires cholecystokinin released from entorhinal cortex afferents

eLife
The entorhinal cortex is involved in establishing enduring visuo-auditory associative memory in the neocortex. Here we explored the mechanisms underlying this synaptic plasticity related to projections from the visual and entorhinal cortices to the ...

Physical Exercise Promotes Novel Object Recognition Memory in Spontaneously Hypertensive Rats after Ischemic Stroke by Promoting Neural Plasticity in the Entorhinal Cortex

Frontiers in Behavioral Neuroscience, 2017
Cerebral ischemia leads to memory impairment, and several studies have indicated that physical exercise (PE) has memory-improving effects after ischemia. This study was designed to further explore the specific role of PE in novel object recognition (NOR)

Structural Analysis of Brain Hub Region Volume and Cortical Thickness in Patients with Mild Cognitive Impairment and Dementia

Medicina, 2020
Background and Objectives: A complex network of axonal pathways interlinks the human brain cortex. Brain networks are not distributed evenly, and brain regions making more connections with other parts are defined as brain hubs.

The human entorhinal cortex: A cytoarchitectonic analysis

Journal of Comparative Neurology, 1995
AbstractThe entorhinal cortex of man is in the medial aspect of the temporal lobe. As in other mammalian species, it constitutes an essential component of the hippocampal formation and the route through which the neocortex interacts with the hippocampus.

Distribution of calcium-binding proteins immunoreactivity in the bottlenose dolphin entorhinal cortex

Frontiers in Neuroanatomy
IntroductionThe entorhinal cortex has been shown to be involved in high-level cognitive functions in terrestrial mammals. It can be divided into two main areas: the lateral entorhinal area (LEA) and the medial entorhinal area (MEA).

Complementary Roles of Hippocampus and Medial Entorhinal Cortex in Episodic Memory

Neural Plasticity, 2008
Spatial mapping and navigation are figured prominently in the extant literature that describes hippocampal function. The medial entorhinal cortex is likewise attracting increasing interest, insofar as evidence accumulates that this area also contributes ...

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 ...
