Every day the human brain is presented with tasks ranging from the trivial to the complex. How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness. Now a study from Massachusetts General Hospital (MGH) researchers finds that a structure deep within the brain, […]
New pictures from the University of Iowa show what it looks like when a person runs out of patience and loses self-control. A study by University of Iowa neuroscientist and neuro-marketing expert William Hedgcock confirms previous studies that show self-control is a finite commodity that is depleted by use. Once the pool has dried up, […]
Scientists have shown that the brains of people with depression respond differently to feelings of guilt – even after their symptoms have subsided. University of Manchester researchers found that the brain scans of people with a history of depression differed in the regions associated with guilt and knowledge of socially acceptable behaviour from individuals who […]
New research shows that sleep loss markedly exaggerates the degree to which we anticipate impending emotional events, particularly among highly anxious people, who are especially vulnerable. Two common features of anxiety disorders are sleep loss and an amplification of emotional response. Results from the new study suggest that these features may not be independent of […]
Scientists studying the Chinese mindfulness meditation known as integrative body-mind training (IBMT) say they have confirmed and expanded their findings on changes in structural efficiency of white matter in the brain that can be related to positive behavioral changes in subjects practicing the technique regularly for a month.
Everyone knows that people vary substantially in how hard they are willing to work, but the origin of these individual differences in the brain remains a mystery. Now the veil has been pushed back by a new brain imaging study that has found an individual’s willingness to work hard to earn money is strongly influenced […]
The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid structure with no diagonals, say scientists funded by the National Institutes of Health. Included in this […]
Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. The research was carried […]
