The superior cerebellar artery is the most consistent branch of the basilar artery and arises near the bifurcation of the basilar artery. A bilateral origin of the superior cerebellar arteries from the posterior cerebral arteries has been rarely reported in the literature. Reporting variations in brain vessels is important for neurosurgeons to safely and confidently treat pathologies in this re...

This study used structural magnetic resonance imaging (MRI) to investigate associations between brain structure and saccadic eye movements. Seventeen healthy subjects underwent structural MRI and infra-red oculographic assessment of a reflexive saccade task. Volumes of prefrontal, premotor, and occipitoparietal cortex, caudate, thalamus, and cerebellar vermis were used as predictors in multiple...

The anatomic diversity of the cerebellar arteriovenous malformations requires a classification which is more surgically informative. The selection tools like the Spetzler-Martin grading system are best suited for the cerebral arteriovenous malformations, while they are quite inaccurate for the cerebellar AVMs. For this reason, in order to define the subtypes of cerebellar arteriovenous malforma...

BACKGROUND AND PURPOSE Histologic evidence of cortical tubers is pathognomonic of tuberous sclerosis (TS) disease. Cerebellar tubers, however, are uncommonly found. Our objective was to evaluate the prevalence and characteristics of cerebellar tubers in a large series of pediatric patients with TS studied with MR imaging. In particular, their relationship with volume loss and age will be analyz...

BACKGROUND Deposition of cortical amyloid beta (Aβ) is a correlate of aging and a risk factor for Alzheimer disease (AD). While several higher order cognitive processes involve functional interactions between cortex and cerebellum, this study aims to investigate effects of cortical Aβ deposition on coupling within the cerebro-cerebellar system. METHODS We included 15 healthy elderly subjects ...

OBJECTIVE Childhood-onset schizophrenia is a severe and unremitting form of the disorder. Prospective brain magnetic resonance imaging (MRI) studies have found progressive loss of total cerebral volume during adolescence, primarily attributable to accelerated loss of cortical gray matter. Because there is evidence of cerebellar involvement in schizophrenia, the authors examined cerebellar volum...

The purpose of the study was to determine craniotopographic (craniometric) indicators sinuous-liquor relationships in horizontal plane people first and second periods mature age, based on maximum permissible depth its introduction. Materials methods. object dura mater brain with sinuses, ventricles vault skull people. performed 100 corpses different ages gender manufacturing native preparations...

We studied the effect of acetazolamide on cerebellar blood flow in 11 stroke patients with large, unilateral cerebral hemispheric infarcts and no evidence of cerebellar infarction, but with cerebrocerebellar diaschisis of cerebral blood flow. Blood flow was determined with xenon-133 inhalation and dynamic single-photon emission computed tomography at rest and 20 minutes after the intravenous in...
