Recent studies suggest that the subventricular zone (SVZ) of the lateral ventricle is populated by heterogeneous populations of stem and progenitor cells that, depending on their exact location, are biased to acquire specific neuronal fates. This newly described heterogeneity of SVZ stem and progenitor cells underlines the necessity to develop methods for the accurate quantification of SVZ stem...

The filling patterns of a negative contrast material (air), a positive contrast water soluble material (Conray), and a positive contrast water insoluble material (Myodil) were examined in 60 normal ventriculograms. Using a scoring system developed for this study, Conray was found effective for outlining the ipsilateral (injected) lateral ventricle, the third ventricle, the aqueduct of Sylvius, ...

BACKGROUND Hydrocephalus caused by unilateral foramen of Monro (FM) obstruction has been referred to in literature by many different terminologies. Precise terminology describing hydrocephalus confined to just one lateral ventricle has a very important prognostic value and determines whether or not the patient can be shunt free after an endoscopic procedure. METHODS Aiming to define the best ...

Background: Intracranial supratentorial neuroenteric cysts are very rare lesions in the central nervous system. We described a neuroenteric cyst of the left lateral ventricle in a 38-year old male, which had been confirmed by using immunohistochemistry. To date,this was the first reported case in which the neuroenteric cyst was located in the lateral ventricle. Case presentation: The patient ha...

OBJECTIVE Schizophrenia is a neurodevelopmental disorder associated with abnormalities of brain structure and white matter, although little is known about when these abnormalities arise. This study was conducted to identify structural brain abnormalities in the prenatal and neonatal periods associated with genetic risk for schizophrenia. METHOD Prenatal ultrasound scans and neonatal structura...

BACKGROUND AND PURPOSE Feasibility of brain atrophy measurement in patients with MS in clinical routine, without prior standardization of the MRI protocol, is unknown. Our aim was to investigate the feasibility of brain atrophy measurement in patients with MS in clinical routine. MATERIALS AND METHODS Multiple Sclerosis and Clinical Outcome and MR Imaging in the United States (MS-MRIUS) is a ...

Neuroepithelial stem cells (NEPs) demonstrate a high potential for self-renewal and differentiation during embryonic development. To explore the survival and differentiation of NEPs in vivo, we isolated NEPs from green fluorescence protein (GFP) transgenic embryos and transplanted into the lateral ventricle of rats. In vitro culture, NEPs proliferated into neurospheres and differentiated into b...

AIMS To establish normal ranges, in preterm infants < 33 weeks' gestation, for measurements of the lateral, third, and fourth ventricles and to assess intra-observer and inter-observer reliability. To assess the effect of head position during scanning on lateral ventricle size. To determine whether sex influences ventricle size. METHODS A prospective study involving infants < 33 weeks' gestat...

OBJECTIVE To examine the possible association between aneuploidies and fetal lateral cerebral ventriculomegaly in the first trimester of pregnancy. METHODS Three-dimensional brain volumes were acquired by transvaginal ultrasound examination at 11-13 weeks' gestation in 410 euploid fetuses and 63 fetuses with trisomy 21, 34 with trisomy 18 and seven with trisomy 13. Lateral ventricles were ass...
