Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
A peek inside the brains of more than 750 children and teens reveals a key difference in...
Researchers have used brain scans to predict how young children learn to read, giving...
A new study shows how schizophrenia is associated with increased rates and intensity of...
Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.
A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.
The human brain is capable of a neural workaround that compensates for the buildup of beta-amyloid, a destructive protein associated with Alzheimer’s disease, according to a new study.
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms.
Using human induced pluripotent stem cells (hiPSCs), researchers have discovered that neurons from patients with schizophrenia secrete higher amounts of three neurotransmitters broadly implicated in a range of psychiatric disorders.
Employing a measure rarely used in sleep apnea studies, researchers uncovered evidence of what may be damaging the brain in people with the sleep disorder— weaker brain blood flow.
People who are obese may be more susceptible to environmental food cues than their lean counterparts due to differences in brain chemistry that make eating more habitual and less rewarding, according to a new study.
Taking benzodiazepines (widely prescribed drugs to treat anxiety and insomnia) is associated with an increased risk of developing Alzheimer's disease, particularly for long-term users, suggests a new study.
Scientists have discovered a novel cause of glaucoma in an animal model, and related to their findings, are now developing an eye drop aimed at curing the disease. They believe their findings will be important to human glaucoma.
Some people avoid risks at all costs, while others will put their wealth, health, and safety at risk without a thought. Researchers have found that the volume of the parietal cortex in the brain could predict where people fall on the risk-taking spectrum.
Scientists have developed a mathematical and computational technology that allows researchers to more accurately map the large, long connections within the white matter tissue of living human brains.
Groundbreaking new research has discovered a new way to preserve the flexibility and resilience of the brain. The study reveals a nerve cell protective molecular target that is essential for brain plasticity.
Scientists found that xenon, given within hours of the initial brain injury, limits brain damage and improves neurological outcomes in mice, both in the short term and long term.
New research published in the Proceedings of the National Academy of Science (PNAS) shows three genetic variants in humans that can account for a couple of IQ points– but before you get excited, these are only three variants out of likely thousands.
Are humans programmed to tell the truth? Not when lying is advantageous, says a new study. The report ties honesty to a region of the brain that exerts control over automatic impulses.
Working with mice, a multicenter team of researchers has found a new way to reduce the abnormal blood vessel growth and leakage in the eye that accompany some eye diseases.
Key discoveries about breast cancer, Parkinson's disease and the body's handling of defective proteins have earned prestigious medical awards for five scientists. The Albert and Mary Lasker Foundation announced the winners Monday.
Postmenopausal women who eat foods higher in potassium are less likely to have strokes and die than women who eat less potassium-rich foods, according to new research.
Neurovascular relationships are especially important in the brain. Studies have shown that when neurons work hard, blood flow increases to keep them nourished. Scientists have been asking whether neural activity also changes the structure of local vascular networks. According to new research, the answer is yes.
Were Albert Einstein and Leonardo da Vinci born brilliant or did they acquire their intelligence through effort? No one knows for sure, but telling people the latter– that hard work trumps genes– causes instant changes in the brain and may make them more willing to strive for success, indicates a new study.
Researchers are investigating markers for potential earlier diagnosis and treatment of Parkinson's disease. The researchers are studying the molecular basis of non-motor symptoms of Parkinson's disease, rather than the better-known clinical symptoms of impaired movement.
An international team of researchers has identified a new inherited neuromuscular disorder. The rare condition is the result of a genetic mutation that interferes with the communication between nerves and muscles, resulting in impaired muscle control.
Sleep difficulties may be linked to faster rates of decline in brain volume, according to a new study. Sleep has been proposed to be “the brain’s housekeeper,” serving to repair and restore the brain.
On this episode of Bioscience Technology This Week, Christina Jakubowski reveals that probing the brain with electric currents can improve memory. Our second story highlights the relationship between individuals and their personalized microbes.
Cancerous brain tumors are notorious for growing back despite surgical attempts to remove them. But scientists are currently developing a new way to try to root out malignant cells during surgery so fewer or none get left behind to form new tumors.
