Published Soccer heading linked to measurable decline in brain function (via sciencedaily.com)
New research links soccer heading -- where players hit the ball with their head -- to a measurable decline in the microstructure and function of the brain over a two-year period.
Published Eye-safe laser technology to diagnose traumatic brain injury (via sciencedaily.com)
Researchers have designed and developed a novel diagnostic device to detect traumatic brain injury (TBI) by shining a safe laser into the eye.
Published Researchers find connections between neuroinflammation and Alzheimer's disease (via sciencedaily.com)
Investigators revealed how genetic changes in certain types of brain cells may contribute to the inflammatory response seen in Alzheimer's disease.
Published Heart over head? Stages of the heart's cycle affect neural responses (via sciencedaily.com) Original source
Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to new research. The sequence of contraction and relaxation is linked to changes in the motor system and its ability to respond to stimulation, and this could have implications for treatments for depression and stroke that excite nerve cells.
Published Fat cells help repair damaged nerves (via sciencedaily.com) Original source
Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process.
Published Repairing nerve cells after injury and in chronic disease (via sciencedaily.com) Original source
Researchers discovered a mechanism for repairing damaged nerves during peripheral neuropathy in mice, wherein the protein Mitf orchestrates nerve repair after both trauma-induced and chronic nerve damage conditions, like Charcot Marie Tooth disease. Their findings may inspire novel therapeutics that bolster repair function and heal peripheral neuropathy -- even in hereditary and developmental cases.
Published Discrimination during pregnancy can affect infant's brain circuitry (via sciencedaily.com) Original source
Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.
Published Innovative design achieves tenfold better resolution for functional MRI brain imaging (via sciencedaily.com) Original source
Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain maladies.
Published Lowering a form of brain cholesterol reduces Alzheimer's-like damage in mice (via sciencedaily.com) Original source
Researchers have found that a form of cholesterol known as cholesteryl esters builds up in the brains of mice with Alzheimer's-like disease, and that clearing out the cholesteryl esters helps prevent brain damage and behavioral changes.
Published Our brains are not able to 'rewire' themselves, despite what most scientists believe, new study argues (via sciencedaily.com) Original source
Contrary to the commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of sight, an amputation or stroke, for example, say scientists. The researchers argue that the notion that the brain, in response to injury or deficit, can reorganize itself and repurpose particular regions for new functions, is fundamentally flawed -- despite being commonly cited in scientific textbooks. Instead, they argue that what is occurring is merely the brain being trained to utilize already existing, but latent, abilities.
Published Hearing loss is associated with subtle changes in the brain (via sciencedaily.com) Original source
A team of researchers employed hearing tests and magnetic resonance imaging (MRI) to determine whether hearing impairment is associated with differences in specific brain regions and affects dementia risk.
Published Brain hemorrhage cause other than injured blood vessels (via sciencedaily.com) Original source
A new study has revealed a new culprit in the formation of brain hemorrhages that does not involve injury to the blood vessels, as previously believed. Researchers discovered that interactions between aged red blood cells and brain capillaries can lead to cerebral microbleeds, offering deeper insights into how they occur and identifying potential new therapeutic targets for treatment and prevention.
Published New study reveals the genetics of human head shape (via sciencedaily.com) Original source
Researchers have discovered a suite of genes that influence head shape in humans. These findings help explain the diversity of human head shapes and may also offer important clues about the genetic basis of conditions that affect the skull, such as craniosynostosis.
Published Hunger hormones impact decision-making brain area to drive behavior (via sciencedaily.com) Original source
A hunger hormone produced in the gut can directly impact a decision-making part of the brain in order to drive an animal's behavior, finds a new study.
Published A small molecule blocks aversive memory formation, providing a potential treatment target for depression (via sciencedaily.com) Original source
Depression is one of the most common mental illnesses in the world, but current anti-depressants have yet to meet the needs of many patients. Neuroscientists recently discovered a small molecule that can effectively alleviate stress-induced depressive symptoms in mice by preventing aversive memory formation with a lower dosage, offering a new direction for developing anti-depressants in the future.
Published Lab-grown 'small blood vessels' point to potential treatment for major cause of stroke and vascular dementia (via sciencedaily.com) Original source
Scientists have grown small blood vessel-like models in the lab and used them to show how damage to the scaffolding that supports these vessels can cause them to leak, leading to conditions such as vascular dementia and stroke.
Published High levels of maternal stress during pregnancy linked to children's behavior problems (via sciencedaily.com) Original source
Children whose mothers are highly stressed, anxious or depressed during pregnancy may be at higher risk for mental health and behavior issues during their childhood and teen years, according to new research.
Published Study reveals broader impact of Alzheimer's on brain function (via sciencedaily.com) Original source
Scientists have published new evidence that shows changes in brain network patterns that occur in early-stage Alzheimer's disease differ from those associated with normal aging. The findings also show that the impact of Alzheimer's on brain function is broader than previously believed. In addition to detecting characteristic changes in the brain circuits supporting memory and attention as expected, the researchers found distinct changes in circuits involved in sensory and motor processing.
Published New studies of brain activity explain benefits of electroconvulsive therapy (via sciencedaily.com) Original source
Researchers have shed new light on why electroconvulsive therapy has such a high success rate, a mystery that has puzzled doctors and scientists for almost a century. Findings could help improve this controversial treatment.
Published Smaller hippocampus linked to cognitive decline (via sciencedaily.com) Original source
With the rise of new drugs that can target the amyloid-beta plaques in the brain that are an early sign of Alzheimer's disease, new ways are needed to determine whether memory loss and thinking problems are due to Alzheimer's disease or another neurodegenerative disorder. A new study shows that shrinkage in the hippocampus area of the brain is associated with cognitive decline, even in people who don't have amyloid plaques in the brain. The hippocampus plays a role in memory.
