Altered diffusivity of the subarachnoid cisterns in the rat brain following neurological disorders

open access: yesBiomedical Journal, 2023
Background: Although changes in diffusion characteristics of the brain parenchyma in neurological disorders are widely studied and used in clinical practice, the change in diffusivity in the cerebrospinal fluid (CSF) system is rarely reported.

Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Ventricular shape and relative position abnormalities in preterm neonates

open access: yesNeuroImage: Clinical, 2017
Recent neuroimaging findings have highlighted the impact of premature birth on subcortical development and morphological changes in the deep grey nuclei and ventricular system. To help characterize subcortical microstructural changes in preterm neonates,

Ependymal Cilia: Physiology and Role in Hydrocephalus

open access: yesFrontiers in Molecular Neuroscience, 2022
Cerebrospinal fluid (CSF), a colorless liquid that generally circulates from the lateral ventricles to the third and fourth ventricles, provides essential nutrients for brain homeostasis and growth factors during development.

Control of cell division in the adult brain by heparan sulfates in fractones and vascular basement membranes [PDF]

open access: yes, 2010
Regulation of cell division in adult tissues and organs requires the coordination of growth factors at the surface of potentially-dividing cells in specific anatomic loci named germinal niches.

Vitamin D concentration and lateral cerebral ventricle volume in older adults [PDF]

open access: yes, 2012
Scope Vitamin D deficiency is associated with an enlargement of the lateral cerebral ventricles in rodents. The effect of low serum 25-hydroxyvitamin D (25OHD) on lateral cerebral ventricle volume has not been studied yet in humans.

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

open access: yes, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

Reliability of MRICloud automatic segmentation for measuring brain ventricular volumes in Parkinson’s disease patients

open access: yesThe Egyptian Journal of Neurology, Psychiatry and Neurosurgery
Background Parkinson’s disease is the second most common neurodegenerative disease. In Parkinson’s disease, enlargement of the ventricles is expected, and when the normal anatomical shape of the ventricles is distorted, automatic segmentation methods may
