In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals — dopamine and serotonin — are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
The finding gives scientists a path to understand diseases where frequent blood-brain barrier damage occurs, including traumatic brain injury, stroke, epilepsy, Alzheimer’s disease, and Parkinson’s disease.
Research expenditures are up and sponsored awards have increased by 15 percent, building upon the prior year’s expenditure total of $542 million, despite the impact of COVID-19 felt nationally by higher education institutes, according to preliminary fiscal year-end reports.
Starting this week, as students begin to return to campus for the fall semester, the lab’s capacity of 1,000 tests per day will also be dedicated to Virginia Tech students and employees in high-contact roles.
Roanoke-based cancer research startup, Acomhal Research Inc., secured a $399,878 Small Business Technology Transfer grant to determine if a molecule that stalls the spread of invasive brain cancer stem cells can help treat aggressive forms of breast cancer.
Fralin Biomedical Research Institute scientists have revealed how a nonfunctioning version of an ordinary gene impairs brain structure and function. The findings help explain a genetic form of microcephaly — a condition where babies’ heads are small and grow more slowly than their peers' heads.
Research partners across three institutions are opening the nation’s first and only resource center, known as C-PROGRESS, dedicated to promoting clinical trials research in the rapidly expanding field of pediatric rehabilitation.
Supported by a new, five-year, $2.8 million National Institutes of Health grant awarded to Harald Sontheimer, a glial neurobiologist at the Fralin Biomedical Research Institute at VTC, scientists are probing changes caused by aging in the circulatory system in the normal brain and Alzheimer’s disease brain.
The brain’s ventral lateral geniculate nucleus receives signals from the eye, but it is not associated with classical image-forming. In a new study, Fralin Biomedical Research Institute at VTC neuroscientists reveal newly identified brain cell subtypes unique to this region that form a striking layered formation.
Finkielstein, a molecular biologist and an associate professor in the College of Science, will join the Fralin Biomedical Research Institute at VTC on July 1. Her laboratory, which studies how circadian rhythms are involved in breast cancer progression, will move to the Health Sciences and Technology Campus in Roanoke.
Anthony-Samuel LaMantia, a developmental neurobiologist and a professor at the Fralin Biomedical Research Institute at VTC, has been named the new director of the institute’s Center for Neurobiology Research, according to Michael Friedlander, executive director of the research institute and Virginia Tech vice president for health sciences and technology.
Fox, director of the Center for Neurobiology Research at the Fralin Biomedical Research Institute at VTC, will move from his current leadership position into a new role as director of the School of Neuroscience, taking over a position held by founding director Harald Sontheimer.
Sora Shin, a new assistant professor at the Fralin Biomedical Research Institute at VTC, studies how stress can induce psychiatric disorders. She hopes to develop new targeted therapeutics to help patients with mental illness.
A dose of adenovirus hits most people like a common cold – a cough, a fever, maybe a sore throat. But for an unfortunate few, the usually benign bug hacks the heart’s cellular electrical communication system and sometimes proves fatal.
Using CRISPR genome editing in zebrafish, scientists with the Fralin Biomedical Research Institute at VTC linked an undiagnosed human disease with a rare genetic mutation that causes craniofacial abnormalities.
Forty million Americans are infected with a parasite called Toxoplasma gondii. New research by scientists at the Fralin Biomedical Research Institute at VTC describes how brain circuits change as the parasite finds long-term shelter inside brain cells.
The same brain cells designed to stop brain damage fail to support healthy neurons when a cancer grows. New research, led by Stefanie Robel and Harald Sontheimer at the Fralin Biomedical Research Institute at VTC, reveals how gliomas alter astrocytes, a cell type that helps protect neurons and is crucial to preventing seizures.
