NIH grant leads to new understanding of aneurysms
A team led by Juan R. Cebral and Anne M. Robertson (University of Pittsburgh) was awarded a $3.1 million grant from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health. “Improving Cerebal Aneurysm Risk Assessment through Understanding Wall Vulnerability and Failure Modes” focuses on understanding the formation of blebs or secondary outpouchings in the aneurysm wall, their potential link to bacterial infiltration through dental infections, and how these sub-structures affect the vulnerability of the aneurysm and its propensity to rupture.
Cebral also received another $2.9 million grant entitled “Bridging the Gap from Hemodynamic Stress to Intracranial Aneurysm Instability.” This project uses a novel technology developed at UCLA to study the responses of endothelial cells to adverse hemodynamic flow conditions in cerebral aneurysms using in-vitro patient-specific vascular models in combination with in-silico models and clinical and tissue data.

Mike Buschmann and Shani Ross receive a NIH R25 grant “ Clinical Immersion with Health Professionals and Industry Advising in Undergraduate Biomedical Engineering Capstone Design”
Professor and Chair Michael Buschmann and Assistant Professor and Associate Chair Shani Ross were recently awarded a $198k R25 Team-Based Design in Biomedical Engineering Education grant from the National Institutes of Health to develop a new senior year capstone design course and summer clinical immersion program for Bioengineering students at George Mason University. Students will engage in a clinical immersion program over the summer at participating clinical sites to identify clinical-relevant needs. Later, in senior design, they will work alongside students from nursing and health administration to develop solutions for these unmet needs following a medical product development process. The design teams will be supported by multidisciplinary advising teams comprising faculty from Bioengineering, Nursing, Health Informatics and Health Policy; as well as from industry partners on the department’s advisory board. This multidisciplinary collaboration brings together faculty and students from bioengineering and CHHS, clinical partners from Inova Fairfax Medical Campus, Children’s National Medical Center, and Georgetown University Medical Center; and industry partners from the Mason Bioengineering Alliance.

A new upgrade to Hippocampome.org, an open source tool developed by Dr. Ascoli and team in George Mason University - Volgenau School of Engineering has been integrated with data generated from researchers at the Institute Cajal of Spanish Research Council. This advancement, recently published in PLoS Biology [doi], "will allow the annotation and classification of high-density brain recordings, critical for brain machine interfaces".

Giorgio Ascoli awarded $1.3M RF1 NIH grant from the National Institute of Mental Health entitled “Long-range neuronal projections: circuit blueprint or stochastic targeting?"
Individual nerve cells extending their arbors throughout the brain underlie functional connectivity and cognitive operations. Despite recent technological breakthroughs allowing the continuous accumulation of substantial amounts of whole-brain, single-neuron reconstructions, we still do not know whether these anatomical patterns constitute highly specific circuit motifs or simply reflect random variation within the known constraints of regional connections. This project will rigorously and systematically identify the first comprehensive axon projection “parts list” of a mammalian brain, quantifying for each neuronal class the population size, computational properties, and possible role in neural network function and dysfunction.
