The microsurgical anatomy of the superficial cortical veins was examined in 20 cerebral hemispheres. The superficial cortical veins are divided into three groups based on whether they drain the lateral, medial, or inferior surface of the hemisphere. The veins on the three surfaces are further subdivided on the basis of the lobe and cortical area that they(More)
The surgical approaches to the cavernous sinus were examined in 50 adult cadaveric cavernous sinuses using magnification of X3 to X40. The following approaches were examined: 1) the superior intradural approach directed through a frontotemporal craniotomy and the roof of the cavernous sinus; 2) the superior intradural approach combined with an extradural(More)
The microsurgical anatomy of the choroidal fissure was examined in 25 cadaveric heads. The choroidal fissure, the site of attachment of the choroid plexus in the lateral ventricle, is located between the fornix and thalamus in the medial part of the lateral ventricle. The choroidal fissure is divided into three parts: (a) a body portion situated in the body(More)
The anterior perforating arteries, the group of arteries that enter the brain through the anterior perforated substance (APS), were examined using X 3 to X 40 magnification in 50 cerebral hemispheres obtained from 25 adult cadavers. These arteries arose from the internal carotid, middle and anterior cerebral, and the anterior choroidal arteries. The carotid(More)
The anatomy needed to plan microoperative approaches to the lateral ventricles was examined in 20 cadaveric cerebral hemispheres. The neural, arterial, and venous structures in the walls of the lateral ventricles and the relationship of the lateral ventricles to the third ventricle and basal cisterns were examined. The operative approaches to the lateral(More)
The microsurgical anatomy of the tentorial incisura was evaluated in 25 adult cadavers using X 3 to X 40 magnification. The area surrounding the incisura is divided into the anterior, middle, and posterior incisural spaces. The anterior incisural space is located anterior to the brain stem and extends upward around the optic chiasm to the subcallosal area;(More)
BACKGROUND AND PURPOSE In neuro-oncology, a major problem is clear identification of tumor from the surrounding normal tissue. We hypothesized that we could use the blood oxygen level-dependent functional MR imaging (BOLD fMRI) signals from tumors and normal brain to identify the tumors and distinguish them from the surrounding brain. MATERIALS AND(More)
Our turbulent lengthscale, velocity and diffusivity scalings are compared with data from other numerical, laboratory and field experiments. Comparison is made with reference to the turbulence intensity measure /νN 2. We showed that our turbulent lengthscale and velocity results are consistent with measurements from the experiments considered, and that the(More)
INTRODUCTION In preclinical models, Neuro-Spinal Scaffold (NSS) implantation following spinal cord injury (SCI) promotes neural sparing and regeneration through internal decompression and tissue remodeling. Rather than typical postinjury cyst formation, the NSS acts through appositional healing to form neuropermissive remodeled tissue. A pilot study of the(More)
This study reports the results of a content analysis conducted to determine how academic libraries use the Web to provide help or deliver instruction to users. The researcher used conceptual analysis to determine the number and percent of links provided and relational analysis to examine the categorization and placement of help or instruction links on the(More)
