Reduced ictogenic potential of 4-aminopyridine in the perirhinal and entorhinal cortex of kainate-treated chronic epileptic rats

Neurobiology of Disease, 2008
We investigated the potential of 4-AP (50–100 μM) to induce seizure-like events (SLEs) in combined entorhinal cortex–hippocampal slices from Sprague Dawley rats which developed spontaneous limbic seizures following kainic acid induced status epilepticus.

Effect of reward on electrophysiological signatures of grid cell population activity in human spatial navigation

Scientific Reports, 2021
The regular equilateral triangular periodic firing pattern of grid cells in the entorhinal cortex is considered a regular metric for the spatial world, and the grid-like representation correlates with hexadirectional modulation of theta (4–8 Hz) power in

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Analysis of individualized brain–gut association networks and transcriptional patterns in major depressive disorder

Interdisciplinary Medicine, EarlyView.
Individualized brain–gut association networks suggest potential neuropathological mechanisms in MDD and MDDSI. Multilevel brain–gut association changes involving HSV‐1 and inflammation may be relevant to MDD, whereas alterations related to insulin metabolism may play a potential role in the neuropathological mechanisms of MDDSI.

Co‐ and Multi‐Pathologies in Parkinson's Disease: An International Parkinson and Movement Disorder Society Scientific Issues Committee Review

Movement Disorders, EarlyView.
Abstract Parkinson's disease (PD) has been historically defined as a disease of striatal dopamine deficiency secondary to degeneration of dopaminergic neurons in the substantia nigra pars compacta, related to the presence of Lewy bodies and Lewy neurites.

A mouse model of early sporadic tau pathology induces neurogenic plasticity in the hippocampus.

PLoS ONE
Alzheimer's disease varies by sex but is broadly characterized by widespread neurodegeneration and the accumulation of insoluble amyloid plaques and neurofibrillary tangles.

Shared rhythmic subcortical GABAergic input to the entorhinal cortex and presubiculum

eLife, 2018
Rhythmic theta frequency (~5–12 Hz) oscillations coordinate neuronal synchrony and higher frequency oscillations across the cortex. Spatial navigation and context-dependent episodic memories are represented in several interconnected regions including the

Functional subregions of the human entorhinal cortex

eLife, 2015
The entorhinal cortex (EC) is the primary site of interactions between the neocortex and hippocampus. Studies in rodents and nonhuman primates suggest that EC can be divided into subregions that connect differentially with perirhinal cortex (PRC) vs parahippocampal cortex (PHC) and with hippocampal subfields along the proximo-distal axis. Here, we used

Heterogenous Neuropathology in a Pedigree with RAB39B‐Related Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background In 2015, we reported a family with Parkinson's disease resulting from the RAB39B p.G192R (c.574G>A) variant. Since then, two affected brothers from the family have undergone autopsy. Objectives To characterize neuropathological findings, assess intracellular distribution of RAB39B protein, and examine the effect of p.G192R on α ...

Greater Motor and Nonmotor Burden at Diagnosis Is Associated With Amyloid Copathology in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Concurrent Alzheimer's disease pathology is increasingly recognized as a poor prognostic factor in Parkinson's disease (PD), yet reliable clinical indicators for early identification of AD copathology remain poorly established.
