Researchers identify brain regions involved in seeking information about negative events

The term “doomscrolling” describes the act of endlessly scrolling through bad news on social media and reading every worrisome tidbit that pops up, a habit that unfortunately seems to have become common during the COVID-19 pandemic. The biology of our brains may play a role in that. Researchers at Washington University School of Medicine in …

Study finds brain areas involved in seeking information about bad possibilities

Ilya Monosov, PhD, shows data on brain activity obtained from monkeys as they grapple with uncertainty. Monosov and colleagues at Washington University School of Medicine in St. Louis have identified the brain regions involved in choosing whether to find out if a bad event is about to happen.

Study sheds light on treatment options for devastating childhood brain cancer

Study sheds light on treatment options for devastating childhood brain cancer

A new study led by Washington University School of Medicine in St. Louis provides new guidance on the treatment of medulloblastoma, a pediatric brain cancer. Some aspects of radiation therapy may be reduced while still providing effective treatment. Shown is a proton therapy plan for a patient with medulloblastoma. An extra “boost” radiation dose to …

MRI-guided focused ultrasound advances brain and cancer research

MRI-guided focused ultrasound advances brain and cancer research

By 2034, nearly one-quarter of Americans will have reached retirement age, according to the United States Census Bureau. But as people age, the brain becomes more susceptible to developing disorders, such as essential tremor, Parkinson’s disease, and tumors. Clinicians and researchers are looking to emerging noninvasive ways to interact with living brain tissue that can …

COVID-19's impacts on the brain and mind are varied and common

COVID-19’s impacts on the brain and mind are varied and common

Credit: Maridav/Shutterstock Although COVID-19 was first described as a disease of the lungs, as its relentless march has continued we’ve realized that it has a far wider reach in the human body. COVID-19 has been associated with skin rashes, bleeding disorders and structural damage to the heart and kidneys. It has also been implicated in …

Computer simulations of the brain can predict language recovery in stroke survivors

Computer simulations of the brain can predict language recovery in stroke survivors

In a new paper published in Scientific Reports, researchers can predict language recovery in Hispanic patients who speak both English and Spanish fluently–a group of aphasia patients particularly at risk of long-term language loss–using sophisticated computer models of the brain. Credit: Fakurian Design on Unsplash At Boston University, a team of researchers is working to …

After 15 years, deep brain stimulation still effective in people with Parkinson's

After 15 years, deep brain stimulation still effective in people with Parkinson’s

Credit: Pixabay/CC0 Public Domain Deep brain stimulation continues to be effective in people with Parkinson’s disease 15 years after the device is implanted, according to a study published in the June 2, 2021, online issue of Neurology. Researchers found that compared to before deep brain stimulation, study participants continued to experience significant improvement in motor …

Study reveals how HIV prevents the maturation of myelin-making brain cells

Study reveals how HIV prevents the maturation of myelin-making brain cells

It’s long been known that people living with HIV experience a loss of white matter in their brains. As opposed to “gray matter,” which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping them transmit signals quickly and …

“Cognitive clock” emerges as a new way to measure brain health

Researchers from the Rush University Medical Center developed a novel method to monitor the brain health of patients to improve the early diagnosis and treatment of certain diseases including Alzheimer’s disease and dementia. This “cognitive clock,” which is the term that has been coined for this new screening technique, involves measuring an individual’s cognitive age, …

Low levels of BPA exposure can affect prenatal brain development

Low levels of BPA exposure can affect prenatal brain development

Humans are exposed to a bath of chemicals every day. They are in the beds where we sleep, the cars that we drive and the kitchens we use to feed our families. With thousands of chemicals floating around in our environment, exposure to any number is practically unavoidable. Through the work of researchers like Dr. …
