Fewer than 1 in 10 patients with glioblastoma—the most common type of brain cancer—respond to immunotherapy; a new study reveals how to detect patients who may respond.Continue Reading ...
Feb 15 2019 Genetic variation in individual neurons may have big effect as we age Scientists at the University of Virginia School of Medicine have identified a potential explanation for the mysterious death of specific brain cells seen in Alzheimer’s, Parkinson’s and other neurodegenerative diseases. Genetic variations inside individual neurons may explain the mysterious cell […]Continue Reading ...
The neural ‘time windows’ in certain small brain areas contribute to the complex cognitive symptoms of autism, new research suggests. In a brain imaging study of adults, the severity of autistic symptoms was linked to how long these brain areas stored information. The differences in neural timescales may underlie features of autism like hypersensitivity and […]Continue Reading ...
Every 40 seconds, someone in the United States suffers a stroke and available therapies, such as clot busting drugs or clot removal devices, are focused on limiting the extent of brain damage. Now, research from the University of Pittsburgh School of Medicine and the VA Pittsburgh Healthcare System shows that a brain protein called UCHL1 […]Continue Reading ...
There are ethical dilemmas in cases where a person is unresponsive after a major trauma but is awake within (unresponsive wakefulness syndrome) and when a person is brain dead or truly unconscious. In these cases stopping life support can be a tough decision. Researchers collaborating from different centres in France, Belgium, the United Kingdom, the […]Continue Reading ...
Exercising is good for health and there is yet another reason for it. Exercise is known to release certain endogenous hormones called “feel good” hormones or endorphins. Yet another hormone may be released from the body when a person exercises – this is called irisin. Irisin is found to be protective against Alzheimer’s disease finds […]Continue Reading ...
Researchers at the University of Pennsylvania have made important progress in designing a drug that could recover brain function in cases of severe brain damage due to injury or diseases such as Alzheimer’s. Vitaly Sosnovskiy | Shutterstock The work builds on a previous study where the team managed to convert human fetal glial cells called […]Continue Reading ...
Mechanical clot removal has been shown to be safe and effective in stroke patients with minimal damaged brain tissue. Ideal patient selection may also someday hold promise for strokes damaging large areas of brain tissue, according to late breaking science presented at the American Stroke Association’s International Stroke Conference 2019, a world premier meeting for […]Continue Reading ...
What happens in the brain when we feel discomfort? Researchers at Karolinska Institutet in Sweden are now one step closer to finding the answer. In a new study published in the journal Molecular Psychiatry they identify which pathways in the mouse brain control behavior associated with aversion. Scientists have long been interested in how the […]Continue Reading ...
What makes us human, and where does this mysterious property of “humanness” come from? Humans are genetically similar to chimpanzees and bonobos, yet there exist obvious behavioral and cognitive differences. Now, researchers from the Salk Institute, in collaboration with researchers from the anthropology department at UC San Diego, have developed a strategy to more easily […]Continue Reading ...
Stimulating the brain with implanted electrodes is a successful, but very drastic measure. Researchers from Eindhoven University of Technology, Kempenhaeghe, Philips and Gent University will therefore be working on a method to stimulate the brain using electrodes that are placed on the head rather than inside it. Their goal is to customize treatment for patients […]Continue Reading ...
A drug that removes excess iron and toxins from the body after a brain bleed did not show significant improvement in recovery or neurological function at three months after intracerebral hemorrhage (stroke), but showed some benefits at six months, according to late breaking science presented at the American Stroke Association’s International Stroke Conference 2019, a […]Continue Reading ...
A team of investigators from the Massachusetts General Hospital (MGH) Center for Regenerative Medicine has identified a population of brain cells that appears to play a role in calibrating behavioral responses to potentially threatening situations. In their report published in Nature Neuroscience, the researchers describe finding how activation of a specific group of cells in […]Continue Reading ...
By discovering the culprit behind decreased blood flow in the brain of people with Alzheimer’s, biomedical engineers at Cornell University have made possible promising new therapies for the disease. You know that dizzy feeling you get when, after lying down for an extended period, you stand up a little too quickly? That feeling is caused […]Continue Reading ...
Feb 5 2019 Researchers studying male and female marmosets have homed in on the primate brain circuitry responsible for individual differences in overall anxiety. Their findings, published in JNeurosci, show that increasing levels of the neurotransmitter glutamate in the hippocampus normalizes anxious monkeys’ “fight or flight” response. Previous human and animal studies suggest roles for […]Continue Reading ...
