Published Brain waves usually found in sleep can protect against epileptic activity (via sciencedaily.com) Original source
Slow waves that usually only occur in the brain during sleep are also present during wakefulness in people with epilepsy and may protect against increased brain excitability associated with the condition, finds a new study.
Published Loss of auditory nerve fibers uncovered in individuals with tinnitus (via sciencedaily.com) Original source
Researchers have uncovered that tinnitus, an incurable persistent ringing or other sounds in the ears, might result from underlying auditory nerve damage that can't be detected on conventional hearing tests. The work builds upon previous research into cochlear synaptopathy or 'hidden hearing loss,' a difficulty hearing in noisy environments despite showing normal results on hearing tests. The researchers hope these new findings into the mechanisms underlying tinnitus could lead to treatment options.
Published Lost brain function restored in mice after stroke (via sciencedaily.com) Original source
Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy.
Published Distinct brain activity triggered by memories of trauma (via sciencedaily.com) Original source
It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollable thoughts about the incident. But what exactly happens in the brains of PTSD patients as they recall these traumatic events? Are they remembered the same way as, say, the loss of a beloved pet -- or, for that matter, a relaxing walk on the beach?
Published AI may aid in diagnosing adolescents with ADHD (via sciencedaily.com) Original source
Using artificial intelligence (AI) to analyze specialized brain MRI scans of adolescents with and without attention-deficit/hyperactivity disorder (ADHD), researchers found significant differences in nine brain white matter tracts in individuals with ADHD.
Published Soccer heading linked to measurable decline in brain function (via sciencedaily.com) Original source
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 Researchers identify cell signaling pathway controlling melanoma cell metastasis to the brain (via sciencedaily.com) Original source
Researchers have been working to better understand what drives melanoma brain metastasis. They now report on the identification of a cell signaling pathway that regulates the metastatic spread of melanoma cells to the brain.
Published Mindfulness-based intervention shows promise for PTSD in cardiac arrest survivors (via sciencedaily.com) Original source
A novel pilot study incorporating mindfulness into exposure therapy shows promise for reducing symptoms of post-traumatic stress in cardiac arrest survivors. One in three survivors of cardiac arrest survivors develop PTSD, increasing their risk of mortality, yet no specific treatment has been developed for this population.
Published Drugs already licensed could be trialled to potentially treat secondary brain cancer (via sciencedaily.com) Original source
The largest review of papers for brain cancer that has spread from the lungs has found abnormalities in the brain cancer and for which licensed drugs could be clinically trialed to find out if they could treat the disease. The research also found genetic differences between smokers and non-smokers.
Published Eye-safe laser technology to diagnose traumatic brain injury (via sciencedaily.com) Original source
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) Original source
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.
