New Technique for Diagnosing Brain Diseases is Successfully Put to the Test
Hong Chen, PhD, associate professor of biomedical engineering and radiation oncology at Washington University in St. Louis, is dedicated to what may seem like the impossible. “This constant puzzle of what’s happening in my brain.” Chen is referring to all human brains that share this complexity. And getting answers to serious problems can be very […]
NIH funds study of ultrasound with genetics to treat brain disorders
Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the […]
Induction of a torpor-like state with ultrasound
Some mammals and birds have a clever way to preserve energy and heat by going into torpor, during which their body temperature and metabolic rate drop to allow them to survive potentially fatal conditions in the environment, such as extreme cold or lack of food. While a similar condition was proposed for scientists making flights […]
Insight into brain’s waste clearing system may shed light on brain diseases
Like the lymphatic system in the body, the glymphatic system in the brain clears metabolic waste and distributes nutrients and other important compounds. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke. A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has […]

Wearable ultrasound sensors for human brain in development
A submarine can inadvertently reveal its location because of cavitation, a condition that creates bubbles underwater that burst, then emit sound waves that can be detected by sonar. A team of biomedical engineers at Washington University in St. Louis plans to use the same concept to detect cavitation in human brains that may contribute to […]
