Researchers in Germany said changes in brain metabolism explain why anorexic patients have trouble changing their behavior to increase food intake. Dr. Wolfgang Herzog of Heidelberg University Hospital said less than 1 percent of the population suffers from anorexia, but despite intensive treatment, 20 percent to 30 percent of the cases are severe and chronic and about 10 percent of the patients die of the disease. The researchers examined 30 young women with and without anorexia using...

Ready"¦ go! That phrase not only gets your muscles pumping but also starts blood flowing to the appropriate places in the brain. However, researchers at Baylor College of Medicine found that while measurements of electrical activity showed peaks in the "ready" or anticipatory phase, the blood flow in the brain measured by functional magnetic resonance imaging (fMRI) didn't start until "go." The results could have application in some mental disorders such as schizophrenia."Your brain is...

Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior. The research work of the Department of Psychosomatic and General Internal Medicine at Heidelberg University Hospital (Medical Director: Professor Dr. Wolfgang...

 It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness.That has changed with the findings of scientists at Rutgers University in Newark and the University of California, Los Angeles who have developed a highly accurate way to peer into the brain to uncover a person's mental state and what sort of information is...

Study by UCLA, Rutgers neuroscientists provides new insights"If you could read my mind, love, what a tale my thoughts could tell" "”Gordon LightfootCan neuroscience read people's minds? Some researchers, and some new businesses, are banking on a brain imaging technique known as functional magnetic resonance imaging (fMRI) to reveal hidden thoughts, such as lies, truths or deep desires.New research by neuroscientists at UCLA and Rutgers University provides evidence that fMRI can be used...

Ducking a punch or a thrown spear calls for the power of the human brain to process 3-D motion, and to perceive an object (whether it's offensive or not) moving in three dimensions is critical to survival. It also leads to a lot of fun at 3-D movies.Neuroscientists have now pinpointed where and how the brain processes 3-D motion using specially developed computer displays and an fMRI (functional magnetic resonance imaging) machine to scan the brain.They found, surprisingly, that 3-D motion...

Training increases brain processing speed and improves our ability to multitask, new research from Vanderbilt University published in the June 15 issue of Neuron indicates. "We found that a key limitation to efficient multitasking is the speed with which our prefrontal cortex processes information, and that this speed can be drastically increased through training and practice," Paul E. Dux, a former research fellow at Vanderbilt, and now a faculty member at the University of Queensland in...

What is going on in teenagers' brains as their drive for peer approval begins to eclipse their family affiliations? Brain scans of teens sizing each other up reveal an emotion circuit activating more in girls as they grow older, but not in boys. The study by Daniel Pine, M.D., of the National Institute of Mental Health (NIMH), part of National Institutes of Health, and colleagues, shows how emotion circuitry diverges in the male and female brain during a developmental stage in which girls are...

A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman. The surgery was performed at University Hospital by an eight-member team from the Brain Tumor Center at the UC Neuroscience Institute. "This marks the culmination of one of the most important developments in brain tumor surgery in the last 100 years,"...

A new study of the cognitive processes involved with honesty suggests that truthfulness depends more on absence of temptation than active resistance to temptation.Using neuroimaging, psychologists looked at the brain activity of people given the chance to gain money dishonestly by lying and found that honest people showed no additional neural activity when telling the truth, implying that extra cognitive processes were not necessary to choose honesty. However, those individuals who behaved...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
