When investigators applied light-driven stimulation to nerve cells in the brains of mice that had suffered strokes several days earlier, the mice showed significantly greater recovery in motor ability than mice that had experienced strokes but whose brains weren’t stimulated.
A team of researchers has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer’s disease. The current study found that chemical modifications to DNA within the ANK1 gene are strongly associated with measures of neuropathology in the brain.
A genetic variation linked to schizophrenia, bipolar disorder and severe depression wreaks havoc on connections among neurons in the developing brain, a team of researchers reports.
Ever wonder why it’s hard to focus after a bad night’s sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions.
Children with sensory processing disorder (SPD) have decreased white matter brain connections in sensory regions very different from those with autism, say researchers. Their study is the first to compare, and find critical differences in, brain connectivity in autism versus SPD versus controls.
Attention Deficit Hyperactivity Disorder (ADHD) is the most commonly diagnosed—and misdiagnosed—behavioral disorder in children in America, according to the Centers for Disease Control and Prevention. Unfortunately, there are currently no reliable physiological markers to diagnose ADHD.
It has been more than 20 years since scientists discovered that mutations in the gene huntingtin cause the devastating progressive neurological condition Huntington’s disease. Surprisingly little, however, has been known about the gene’s role in normal brain activity. Now, new research shows it plays a critical role in long-term memory.
Dangerous brain tumors hijack the brain’s existing blood supply throughout their progression, by growing only within narrow potential spaces between and along the brain’s thousands of small blood vessels, new research shows for the first time.
Blood expression levels of genes targeted by the stress hormones called glucocorticoids could be a physical measure, or biomarker, of risk for developing Post-Traumatic Stress Disorder (PTSD), according to a new study.
Playing with the portions of good and not-so-good-for-you foods is better than trying to eliminate bad foods, according to a new study. The idea is to not give up entirely foods that provide pleasure but aren’t nutritious.
Cognitive abilities such as memory and attention are not only important after a stroke but also before. Previous studies have shown poor cardiovascular health can increase the risk of cognitive impairment such as problems in memory and learning. However, the opposite idea that cognitive impairment may impact cardiovascular health, specifically stroke, was not established before.
At least one part of the human brain may be able to process information the same way in older age as it does in the prime of life, according to new research conducted at the University of Adelaide. A study compared the ability of 60 older and younger people to respond to visual and non-visual stimuli in order to measure their "spatial attention" skills.
A nasal brush test can rapidly and accurately diagnose Creutzfeldt-Jakob disease (CJD), an incurable and ultimately fatal neurodegenerative disorder, according to a new study.
In the largest study of its kind, researchers suggests that in older people, not getting enough vitamin D may double the risk of developing dementia and Alzheimer’s disease.
In this episode of Bioscience Technology This Week, News Editor Christina Jakubowski highlights the role of the protein GSK-3 in brain development and also reports that running, regardless of duration or speed, reduces death risk.
Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism (how the brain generates the energy it needs to function) and aggression.
Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is— while many animals have this ability, humans don't. But now, new research suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits.
A team of scientists has developed an entirely non-invasive technique that provides a view of blood flow in the brain. The tool could provide powerful insights into strokes and possibly Alzheimer's disease.
Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine. The findings add to growing evidence that lifestyle factors contribute to brain health later in life.
The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person’s brain responds to threats, according to a new study.
Scientists have discovered that a compound isolated from the plant protects cells from altered molecular pathways linked to Alzheimer’s, Parkinson’s and the neurodegeneration that often follows a stroke.
Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons. The research outlines the advancement in detoxifying organophosphates, which are compounds commonly used in pesticides and warfare agents.
A new study gives insight into the relationship between depression and dementia. The current study, which involved 1,764 people from the Religious Orders Study and the Rush Memory and Aging Project, indicates that the association of depression with dementia is independent of dementia-related brain changes.
Researchers have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice “called” to each other.
The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new study. Instead of changing to accommodate a job, connectivity in key brain networks of autistic children looks similar to connectivity in the resting brain. And the greater this inflexibility, the more severe the child’s manifestations of repetitive and restrictive behaviors that characterize autism, the study found.
