What the brain really thinks about forever chemicals

The human-made chemicals that make our kitchen pans stick-free, our athletic wear water-repellent and firefighting chemicals more efficient do their jobs incredibly well, but it’s at the expense of lingering in the body and environment for what is believed to be forever. These forever chemicals, perfluorooctane sulfonate and perfluorooctanoic acid, more commonly known as PFOS

Many moms-to-be are stressed, and it might affect baby’s brain

(HealthDay)—Many mothers-to-be feel overwhelmed by stress, and it might have implications for their babies’ brain development in the womb, a new study suggests. The researchers found that even in a group of highly educated, healthy pregnant women, stress and anxiety were common. More than one-quarter reported higher-than-average levels of “perceived stress,” while a similar number

Zika virus’ key into brain cells ID’d, leveraged to block infection and kill cancer cells

Zika virus infection can stunt neonatal brain development, a condition known as microcephaly, in which babies are born with abnormally small heads. To determine how best to prevent and treat the viral infection, scientists first need to understand how the pathogen gets inside brain cells. Employing different approaches to answer different questions, two research teams

Speech-disrupting brain disease reflects patients’ native tongue

English and Italian speakers with dementia-related language impairment experience distinct kinds of speech and reading difficulties based on features of their native languages, according to new research by scientists at the UC San Francisco Memory and Aging Center and colleagues at the Neuroimaging Research Unit and Neurology Unit at the San Raffaele Scientific Institute in

Missing protein in brain causes behaviors mirroring autism

Scientists at Rutgers University-Newark have discovered that when a key protein needed to generate new brain cells during prenatal and early childhood development is missing, part of the brain goes haywire—causing an imbalance in its circuitry that can lead to long-term cognitive and movement behaviors characteristic of autism spectrum disorder. “During brain development, there is

Can brain injury from boxing, MMA be measured?

For boxers and mixed martial arts (MMA) fighters, is there a safe level of exposure to head trauma? A new study shows different effects in the brain for younger, current fighters compared to older, retired fighters. The study is published in the December 23, 2019, online issue of Neurology, the medical journal of the American

Using machine learning tools to reveal how memories are coded in the brain

Researchers working in The N.1 Institute for Health at NUS, led by Assistant Professor Camilo Libedinsky from NUS Psychology, and Senior Lecturer Shih-Cheng Yen from the Innovation and Design Programme at NUS Engineering, have discovered that a population of neurons in the brain’s frontal lobe contain stable short-term memory information within dynamically-changing neural activity. This

Scientists develop a new method to detect light in the brain

Researchers from Istituto Italiano di Tecnologia (IIT) and University of Salento, both in Lecce, Italy, and Harvard Medical School in Boston have developed a new light-based method to capture and pinpoint the epicenter of neural activity in the brain. The approach, described in Nature Methods, lays the foundation for novel ways to map connections across

Smokers and hypertensive individuals have higher risk of sudden death from brain bleed than previously believed

Contrary to the previous data, a Finnish study clarifies that smoking and high blood pressure do not protect from death in patients suffering from subarachnoid hemorrhage, the most lethal stroke subtype. In fact, subarachnoid hemorrhage kills smokers and hypertensive individuals even before they reach hospitals, and therefore, previous studies that did not include these deaths

Researchers study social communication in pediatric traumatic brain injury

Kessler Foundation researchers conducted a pilot study to determine ways to assess social communication difficulties in children with impaired social functioning caused by moderate-to-severe traumatic brain injury (TBI). The article, “The relationship between social communication and social functioning in pediatric TBI: A pilot study” was epublished on August 14, 2019 by Frontiers in Neurology. The
