From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

Rabies (and rabies virus, its causative agent) is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. Continue reading

Junk food makes rats lose appetite for balanced diet

Junk food makes rats lose appetite for balanced diet

A diet of junk food not only makes rats fat, but also reduces their appetite for novel foods, a preference that normally drives them to seek a balanced diet, reports a study published in the open-access journal Frontiers in Psychology . The study helps to explain how excessive consumption of junk food can change behavior, weaken self-control and lead to overeating and obesity Continue reading

Brain benefits from weight loss following bariatric surgery

Weight loss surgery can curb alterations in brain activity associated with obesity and improve cognitive function involved in planning, strategizing and organizing, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism ( JCEM ). Obesity can tax the brain as well as other organs Continue reading

Taking pulse of aging of the brain

Taking pulse of aging of the brain

Researchers at the Beckman Institute at the University of Illinois at Urbana-Champaign have developed a new technique that can noninvasively image the pulse pressure and elasticity of the arteries of the brain, revealing correlations between arterial health and aging. Brain artery support, which makes up the cerebrovascular system, is crucial for healthy brain aging and preventing diseases like Alzheimer’s and other forms of dementia. Continue reading

Brain imaging shows brain differences in risk-taking teens

Brain imaging shows brain differences in risk-taking teens

According to the CDC, unintentional injuries are the leading cause of death for adolescents. Compared to the two leading causes of death for all Americans, heart disease and cancer, a pattern of questionable decision-making in dire situations comes to light in teen mortality. New research from the Center for BrainHealth at The University of Texas at Dallas investigating brain differences associated with risk-taking teens found that connections between certain brain regions are amplified in teens more prone to risk Continue reading

On the frontiers of cyborg science: Development of electronic-brain relationship

On the frontiers of cyborg science: Development of electronic-brain relationship

No longer just fantastical fodder for sci-fi buffs, cyborg technology is bringing us tangible progress toward real-life electronic skin, prosthetics and ultraflexible circuits. Now taking this human-machine concept to an unprecedented level, pioneering scientists are working on the seamless marriage between electronics and brain signaling with the potential to transform our understanding of how the brain works — and how to treat its most devastating diseases. Their presentation is taking place at the 248th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society. Continue reading

Regular marijuana use bad for teens’ brains

Regular marijuana use bad for teens’ brains

Frequent marijuana use can have a significant negative effect on the brains of teenagers and young adults, including cognitive decline, poor attention and memory, and decreased IQ, according to psychologists discussing public health implications of marijuana legalization at the American Psychological Association’s 122nd Annual Convention. “It needs to be emphasized that regular cannabis use, which we consider once a week, is not safe and may result in addiction and neurocognitive damage, especially in youth,” said Krista Lisdahl, PhD, director of the brain imaging and neuropsychology lab at University of Wisconsin-Milwaukee Continue reading
