Grid alignment in entorhinal cortex [PDF]

Biological Cybernetics, 2012
The spatial responses of many of the cells recorded in all layers of rodent medial entorhinal cortex (mEC) show a triangular grid pattern, and once established might be based in part on path-integration mechanisms. Grid axes are tightly aligned across simultaneously recorded units.

Electrical Stimulation of the Lateral Entorhinal Cortex Causes a Frequency-Specific BOLD Response Pattern in the Rat Brain

Frontiers in Neuroscience, 2019
Although deep brain stimulation of the entorhinal cortex has recently shown promise in the treatment of early forms of cognitive decline, the underlying neurophysiological processes remain elusive.

Teneurins assemble into presynaptic nanoclusters that promote synapse formation via postsynaptic non-teneurin ligands

Nature Communications, 2022
Extensive studies concluded that homophilic interactions between pre- and postsynaptic teneurins, evolutionarily conserved cell-adhesion molecules, encode the specificity of synaptic connections.

Parallel and convergent processing in grid cell, head-direction cell, boundary cell, and place cell networks. [PDF]

, 2013
The brain is able to construct internal representations that correspond to external spatial coordinates. Such brain maps of the external spatial topography may support a number of cognitive functions, including navigation and memory.

Grid Cell Hexagonal Patterns Formed by Fast Self-Organized Learning within Entorhinal Cortex [PDF]

, 2009
Grid cells in the dorsal segment of the medial entorhinal cortex (dMEC) show remarkable hexagonal activity patterns, at multiple spatial scales, during spatial navigation. How these hexagonal patterns arise has excited intense interest. It has previously

Correlation Analysis of the Entorhinal Cortex-Hippocampus Nerve Fiber Changes and Memory Dysfunction in P301L-Tau Mouse Model and Molecular Mechanism

康复学报, 2023
ObjectiveTo observe the correlation between the changes of entorhinal cortex-hippocampus nerve fibers and learning and memory function in the P301L-Tau mouse model of Alzheimer's disease (AD) and related molecular mechanism, so as to provide the evidence

Hippocampal Global Remapping Can Occur without Input from the Medial Entorhinal Cortex. [PDF]

, 2018
The high storage capacity of the episodic memory system relies on distinct representations for events that are separated in time and space. The spatial component of these computations includes the formation of independent maps by hippocampal place cells ...

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.

An Optimized Deep Learning Model for Predicting Mild Cognitive Impairment Using Structural MRI

Sensors, 2023
Early diagnosis of mild cognitive impairment (MCI) with magnetic resonance imaging (MRI) has been shown to positively affect patients’ lives. To save time and costs associated with clinical investigation, deep learning approaches have been used widely to

COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS [PDF]

, 2002
Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The animals’ behavioral changes were then contrasted with those observed earlier (Meunier et al., 1999) in ...
