High Iron And Copper Levels Block Brain-Cell DNA Repair And May Contribute To Neurological Dysfunction

No one knows the cause of most cases of Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is DNA damage by reactive oxygen species, highly destructive molecules usually formed as a byproduct of cellular respiration. Another is the presence of […]

Conclusive Evidence That Stomach Bacteria Influence Brain Chemistry And Behavior

For the first time, researchers at McMaster University have conclusive evidence that bacteria residing in the gut influence brain chemistry and behavior. The findings are important because several common types of gastrointestinal disease, including irritable bowel syndrome, are frequently associated with anxiety or depression. In addition, there has been speculation that some psychiatric disorders, such […]

Weak Electrical Fields In The Brain Help Neurons Fire Together

The brain – awake and sleeping – is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping electric fields, generated by the neural circuits of scores of communicating neurons. The fields were once thought to be an […]

The Neural Origins Of Expert Intuition

What makes experts different from the rest of us? Over the past century, this question has prompted a range of studies on various aspects of human cognition that reveals clues about the psychological and neurological origins of intelligence, perception, and memory. While board games such has chess have provided the most productive setting for such […]

Brain Scans Show Children With ADHD Have Faulty Off-Switch For Mind-Wandering

Brain scans of children with attention-deficit/hyperactivity disorder (ADHD) have shown for the first time why people affected by the condition sometimes have such difficulty in concentrating. The study, funded by the Wellcome Trust, may explain why parents often say that their child can maintain concentration when they are doing something that interests them, but struggles […]

Combined Consumption Of Caffeine And Glucose Improves The Efficiency Of Brain Activity

The combination of caffeine and glucose can improve the efficiency of brain activity, according to a recent study in which functional magnetic resonance imaging was used to identify the neural substrate for the combined effects of these two substances. The results of the study was published in the journal Human Psychopharmacology: Clinical and Experimental.

Researchers Discover How The Brain Is Wired For Attention

University of Utah (U of U) medical researchers have uncovered a wiring diagram that shows how the brain pays attention to visual, cognitive, sensory, and motor cues. The research provides a critical foundation for the study of abnormalities in attention that can be seen in many brain disorders such as autism, schizophrenia, and attention deficit […]
