Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

Experimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Parvalbumin interneurons in Alzheimer's disease: Physiological insights and pathophysiological mechanisms

Journal of Cell Communication and Signaling, Volume 20, Issue 3, September 2026.
Physiological and Pathological Alterations in PV+ Neurons: Under physiological conditions, PV+ interneurons exhibit fast‐spiking properties and generate gamma oscillations at the cost of high energy consumption. In AD, PV+ neurons display abnormalities in ion channels, dendrites, neurotransmission, energy metabolism, and neural oscillations, ultimately

Young Adult Microglial Deletion of C1q Reduces Engulfment of Synapses and Partially Mitigates Cognitive Impairment in an Aggressive Alzheimer's Disease Mouse Model

Glia, Volume 74, Issue 9, September 2026.
Young adult deletion of microglial C1q reduced engulfment of Vglut1+ synapses and mitigated spatial cognitive deficits at 10 months of age in the amyloidopathy Arctic mouse model of AD. Neither fibrillar amyloid plaques nor soluble or insoluble Aβ levels in the hippocampus were affected by young adult microglial loss of C1q despite reduced phagocytosis

An Update on the Model of Connectivity of the Hippocampal Formation (I): The Perforant Pathway to the Dentate Gyrus

Hippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT The hippocampus participates in crucial functions such as memory consolidation, spatial processing and emotional regulation that require diverse input from multiple cortical areas that is funneled through the upper layers of the entorhinal cortex (EC), mostly from layer II to the dentate gyrus (DG).

Hippocampal Subfield Volumetry and Navigation in Congenital Blindness

Hippocampus, Volume 36, Issue 5, September 2026.
ABSTRACT The hippocampus is essential for efficient navigation. Although lack of visual experience from birth induces volumetric and structural modifications to the hippocampus, tactile and auditory navigation remain partially preserved in congenitally blind (CB) individuals.

From regulatory mechanisms to cutting‐edge applications: Research progress of ultrasound, electrical, magnetic, and optical stimulation in neural modulation

Journal of Intelligent Medicine, Volume 3, Issue 3, Page 196-219, September 2026.
Abstract In recent years, the clinical treatment and symptom management of neurological disorders have faced significant challenges due to the high complexity of the nervous system's structure and function. Against this backdrop, physical stimulation techniques have emerged as a vital complementary approach to traditional pharmacological treatments and

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

Status epilepticus and thinning of the entorhinal cortex

Epilepsy & Behavior
Status epilepticus (SE) carries risks of morbidity and mortality. Experimental studies have implicated the entorhinal cortex in prolonged seizures; however, studies in large human cohorts are limited. We hypothesised that individuals with temporal lobe epilepsy (TLE) and a history of SE would have more severe entorhinal atrophy compared to others with ...

Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, Volume 16, Issue 8, Page 809-819, August 2026.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Cross‐ancestry polygenic risk scores enhance Alzheimer's disease risk prediction in multiethnic cohorts

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Genome‐wide association studies (GWAS) have identified 80+ genetic loci associated with Alzheimer's disease (AD), enabling the development of polygenic risk scores (PRS). However, the predictive accuracy of PRS in diverse populations remains low.
