Astrocyte reactivity modifies the effects of locus coeruleus norepinephrine‐related dysfunction on tau and its impact on cognition

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Animal models demonstrated that pharmacologically‐induced lesioning of the locus coeruleus (LC), the brain's primary source of norepinephrine, triggered astrocyte reactivity, exacerbating Alzheimer's disease (AD) pathology and cognitive deficits.

OCCLUSION OF THE POSTERIOR INFERIOR CEREBELLAR ARTERY [PDF]

Journal of the American Medical Association, 1914
The posterior inferior cerebellar artery is usually described as the largest branch of the vertebral artery, and its course as passing obliquely backward around the medulla oblongata, at first between the roots of the hypoglossal nerve, then between the roots of the accessory and the vagus nerves, to end on the inferior surface of the cerebellum.

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Exploring Gray Matter Alterations in Post‐Stroke Patients: A Structural Covariance Analysis

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Background While structural covariance analysis is adept at assessing morphometric correlations among broadly distributed brain regions, limited research has focused on alterations in structural covariance networks post‐stroke. This study aims to identify significant brain gray matter changes and distinct structural covariance patterns in ...

Far Lateral Craniotomy for Posterior Inferior Cerebellar Artery–Posterior Inferior Cerebellar Artery Bypass and Trapping of Posterior Inferior Cerebellar Artery Aneurysm: 3-Dimensional Operative Video

Operative Neurosurgery, 2018
Abstract Posterior inferior cerebellar artery (PICA) aneurysms account for 3% to 4% of all intracranial aneurysms with an unusually high predilection towards a nonsaccular morphology making microsurgical clipping or endovascular reconstruction of the parent artery difficult.

Structural Restoration of an Unruptured Vertebral Artery Dissection Following Autologous Mesenchymal Stem Cell Therapy: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Vertebral artery dissection (VAD) is a recognized cause of ischemic stroke, and current management relies on antithrombotic therapy that is not specifically directed at structural repair of the arterial wall. We report a man in his mid‐50s who presented with a sudden, severe right occipital headache after a golf swing and had a history of a ...

Regression, Ataxia, and Nystagmus in a Toddler: Unraveling a Rare Neurodegenerative Disorder

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Infantile neuroaxonal dystrophy (INAD) should be considered in any toddler presenting with psychomotor regression and cerebellar atrophy, even when basal ganglia iron deposition is absent on initial MRI. Molecular genetic testing of PLA2G6 is essential for definitive diagnosis, enabling accurate genetic counseling and timely multidisciplinary ...

Origin of the Posterior Inferior Cerebellar Artery over the C1 Posterior Arch [PDF]

Revista Brasileira de Ortopedia
Resumo The posterior inferior cerebellar artery usually arises from the intracranial segment (V4) of the vertebral artery. Despite its mean diameter of 2 mm, it usually irrigates important areas of the brain.
