Virginia Tech scientists tie improved learning processes to reduced symptoms of depression

In a Journal of the American Medical Association Psychiatry study led by Pearl Chiu and Brooks King-Casas of the Fralin Biomedical Research Institute at VTC, brain imaging and mathematical modeling reveal previously unreported mechanistic features of symptoms associated with major depressive disorder.

New Study Exposes Potential Expansion Barriers to Functional MRI for Medicare Patients

A new Harvey L. Neiman Health Policy Institute study found that functional magnetic resonance imaging (fMRI) steadily increased from 2007-2014 but has now been static due to potential expansion barriers. This diagnostic imaging method is critical in determining brain functions as well as for assessing the potential risks of surgery or other invasive treatments of the brain. This American Journal of Neuroradiology (AJNR) study is the first of its kind to assess the nationwide adoption of fMRI.

Neuroscientists reveal the basis of confirmation bias

Neuroscientists at Virginia Tech, University College London, and the University of London revealed brain mechanisms that underlie confirmation bias — a phenomenon where people strongly favor information that reinforces existing opinions over contradictory ones.

The study, published this week in Nature Neuroscience, provides insight into a fundamental property of belief formation that has been documented by psychologists and economists, as well as in popular literature, including George Orwell’s “1984.”
