Study reveals link between brain cell development and risk of schizophrenia

Credit: Pixabay/CC0 Public Domain Scientists from Cardiff University have discovered new links between the breakdown in brain cell development and the risk of schizophrenia and other psychiatric disorders. Genetic risk factors are known to disrupt brain development in a number of these disorders, but little is known about which aspects of this process are affected. …

Research on human brain development sheds light on neurodevelopmental disorders

Research on human brain development sheds light on neurodevelopmental disorders

Credit: CC0 Public Domain New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London has found that some processes behind the early development of GABAergic neurons, neurons that produce the main inhibitory chemical messenger in the central nervous system, are consistent between humans and mice. The research, published in Science, …

Asthma may reduce risk of brain tumors—but how?

Asthma may reduce risk of brain tumors—but how?

Credit: Unsplash/CC0 Public Domain There’s not much good that can be said about asthma, a breathing disease in which the airways become narrowed and inflamed. But there’s this: People with asthma seem to be less likely to develop brain tumors than others. And now, researchers at Washington University School of Medicine in St. Louis believe …

Head-mounted microscope allows long-term brain imaging in freely moving mice

Head-mounted microscope allows long-term brain imaging in freely moving mice

Credit: CC0 Public Domain Researchers have developed the first detachable head-mounted photoacoustic microscope for imaging brain activity in freely moving mice. Because the device can be removed after imaging, it enables long-term studies that could reveal important new insights into neurodegenerative diseases and other neurological disorders. “Epilepsy, Alzheimer’s disease and Parkinson’s disease can all seriously …

Saliva analysis of long-term cannabis smokers identifies oral microbiome disruptions that may lead to brain disorders

Saliva analysis of long-term cannabis smokers identifies oral microbiome disruptions that may lead to brain disorders

Credit: CC0 Public Domain More and more states are legalizing marijuana, but little is known about how long-term cannabis use affects the microbes in the oral cavity, known as the oral microbiome. The oral microbiome plays a critical role in maintaining oral health, but changes to the environment in the mouth, such as those caused …

Targeting the brain should be the focus of ALS therapy, not just spinal cord

Targeting the brain should be the focus of ALS therapy, not just spinal cord

The brain is indeed a target for treating ALS (amyotrophic lateral sclerosis), Northwestern Medicine scientists have discovered. This flips a long-standing belief that the disease starts in the spinal motor neurons and any therapy would need to target the spine as the key focus. A new Northwestern study shows the degeneration of brain motor neurons …

Unique brain channel combats epileptic seizures

Unique brain channel combats epileptic seizures

Credit: Pixabay/CC0 Public Domain Epilepsy, a chronic brain disorder that causes seizures, affects around 50 million people worldwide. New research from the lab of Department of Biomedical Sciences Professor Susan Tsunoda that was recently featured in the Journal of Neuroscience showed for the first time that a channel in the brain called dSlo2 suppresses epileptic …

Popular blood thinners may lead to brain bleeding after head injury

The left image shows the initial CT scan of the brain in a patient on both clopidogrel (Plavix) and aspirin who presented to the Emergency Department with head trauma that did not demonstrate any intracranial hemorrhage. The right image shows a head CT obtained 24 hours later demonstrating a large parenchymal hemorrhage in the right …
