p‐Brain: A Modular Open‐Source Framework for Automated Quantitative DCE‐MRI of Cerebral Perfusion, Microvasculature, and Blood–Brain Barrier Permeability

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT We present p‐Brain, a modular, open‐source framework for reproducible, automated quantitative DCE‐MRI at scale. Rather than a fixed pipeline, p‐Brain is built from interchangeable stages (ingestion, T1/M0$$ {T}_1/{M}_0 $$ fitting, vascular and tissue ROI extraction, signal‐to‐concentration conversion, kinetic modeling, and quality control ...

Abstract Number ‐ 268: Sarcoid Induced Posterior Circulation Abnormality With Recurrent Ischemic Strokes

Stroke: Vascular and Interventional Neurology, 2023
Introduction The estimated incidence of Neurosarcoidosis is ∼5‐15%. Most of these cases involve anterior circulation. Here we are presenting a case of recurrent posterior circulation ischemic stroke in a patient with neurosarcoidosis.

Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of

Immune proteomic associations with indices of cortical development in 5‐year‐old children

Journal of Anatomy, EarlyView.
Typically developing 5‐year‐old children (n = 101–126) from the FinnBrain Birth Cohort Study, Finland, underwent both targeted serum immune proteomics and magnetic resonance brain imaging. Multiple inflammatory markers, from one cluster of co‐expressed immune proteins, were negatively associated with indices of cortical development, including thickness,

OCCLUSION OF THE POSTERIOR INFERIOR CEREBELLAR ARTERY [PDF]

Journal of the American Medical Association, 1913
From a clinical and physiologic standpoint, lesions of a limited area, occurring at any level of the brain-stem, are of much interest. Any attempt to analyze the grouping of the afferent impulses in this region has always been attended with considerable difficulty.

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, Volume 309, Issue 10, Page 2560-2573, October 2026.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Surgical Clipping of a Ruptured Posterior Inferior Cerebellar Artery Aneurysm

, 2015
Posterior circulation aneurysms are commonly treated with endovascular techniques. In select cases, microsurgery remains an essential tool for treating these lesions.

Individualized endovascular management of distal posterior circulation aneurysms: a single-center experience and decision framework

Frontiers in Neurology
PurposeDistal intracranial aneurysms (IAs) of the posterior circulation are rare and often pose significant surgical challenges. Although endovascular treatment (EVT) has emerged as an alternative, clear management guidelines remain lacking.
