Carnegie Mellon University neuroscientists have identified a new pathway by which several brain areas communicate within the brain’s striatum.
An over-active habit system may be at the root of many psychological problems involving repetitive behaviours like OCD, alcoholism and binge eating, new research suggests. The neuroimaging study, which is published in the American Journal of Psychiatry, found that people with Obsessive-Compulsive Disorder (OCD) had difficulty controlling their habits.
A new study suggests that the right hemisphere of the brain may be able to assist a damaged left hemisphere in protecting visual attention after a stroke.
Computer based ‘brain training’ can boost memory and thinking skills in older adults, but many programs promoted by the $1 billion brain training industry are ineffective, reveals new research by the University of Sydney.
Researchers have found that navigational brain cells that help sense direction are as electrically active during deep sleep as they are during wake time—and have visual and vestibular cues to guide them. Such information could be useful in treating navigational problems, among the first major symptoms of Alzheimer’s disease and other neurological disorders.
New technology could help researchers advance blood biomarker capabilities that show changes in low concentrations of specific proteins present following a neurological injury.
Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a byproduct of neuron activity, recent studies suggest that these waves may play a critical role in communication between different parts of the brain.
Thousands of genetic “dimmer” switches, regions of DNA known as regulatory elements, were turned up high during human evolution in the developing cerebral cortex, according to new research from the Yale School of Medicine.
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new study reveals.
Finally this week, overall fluid intelligence — the ability to analyze information, engage in critical thinking, and solve problems — is thought to peak in early adulthood, but a new study suggests that different aspects of fluid intelligence peak at different ages.
