A 22-year-old woman known as “HC” with amnesia since birth as a result of developing only half the normal volume of the hippocampus in her brain, has demonstrated to scientists that the ability to hold a single face or word in short-term memory is impaired. Included in this report is a video summary of the […]

Violent Games Can Emotionally Desensitize Players To Aggressive Behavior
After excessively violent events, shoot ’em up games regularly come under scrutiny. In Norway, several first-person shooter games actually disappeared from the market for a while after the killings. Does intense fighting on a flat screen display also result in aggressive behavior in real life? Researchers from the University of Bonn found brain activity patterns […]
Body Weight And Sleep-Disordered Breathing Negatively Impact Cognition In Children
Researchers at the University of Chicago have found important new relationships between obesity, sleep-disordered breathing (SDB) and cognitive processing among elementary school children. Included in this report is a link to download the a copy of the full-text, original study while available. The findings were published online ahead of print publication in the American Thoracic […]
Researcher Urges Scientists To Stop Emphasizing The Shortcomings Of People With Autism
We must stop considering the different brain structure of autistic individuals to be a deficiency, as research reveals that many autistic people – not just “savants” – have qualities and abilities that may exceed those of people who do not have the condition, according to a provocative article published today in Nature by Dr. Laurent […]
Exercise May Improve Brain Fatigue
Researchers have long known that regular exercise increases the number of organelles called mitochondria in muscle cells. Since mitochondria are responsible for generating energy, this numerical boost is thought to underlie many of the positive physical effects of exercise, such as increased strength or endurance. Exercise also has a number of positive mental effects, such […]
Growth Rate Of Premature Babies’ Brain May Predict Ability Certain Cognitive Abilities Later In Childhood.
New research suggests the growth rate of the brain’s cerebral cortex in babies born prematurely may predict how well they are able to think, speak, plan and pay attention later in childhood. The research is published in the October 12, 2011, online issue ofNeurology, the medical journal of the American Academy of Neurology. The cerebral […]
Low Vitamin B12 Levels May Lead To Brain Shrinkage And Cognitive Problems
Older people with low levels of vitamin B12 in their blood may be more likely to lose brain cells and develop problems with their thinking skills, according to a study published in the September 27, 2011, print issue of Neurology, the medical journal of the American Academy of Neurology. Foods that come from animals, including fish, […]
Researchers Decode And Reconstruct The Brain’s Dynamic Visual Experiences
Imagine tapping into the mind of a coma patient, or watching one’s own dream on YouTube. With a cutting-edge blend of brain imaging and computer simulation, scientists at the University of California, Berkeley, are bringing these futuristic scenarios within reach. Using functional Magnetic Resonance Imaging (fMRI) and computational models, UC Berkeley researchers have succeeded in […]
