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...

MENLO PARK, Calif., June 29 /PRNewswire/ -- Kornberg Associates | Architects (www.kornberg.com) has been selected by Stanford University to design a new Cognitive & Neurobiological Imaging Center. Ken Kornberg, president and founder, made the announcement. The firm has worked with Stanford University since 1980 and has completed 20 projects over the past 30 years, one of which is the two-story, 32,000 square-foot office building for the Stanford Linear Accelerator. They are also working...

High levels of brain energy are required to maintain consciousness, a finding which suggests a new way to understand the properties of this still mysterious state of being, Yale University researchers report.At its simplest, consciousness can be defined as the ability to respond meaningfully to external stimuli. Most studies of consciousness have used imaging technology to try to pinpoint areas of brain activity during tasks such as memorization or problem solving.There are two problems with...

According to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, patients suffering from chronic primary insomnia (PIs) have higher levels of brain activation compared to normal sleepers during a working memory test.Results show that PIs use increased brain activation relative to good sleepers during the working memory task, particularly in areas responsible for visual-spatial attention and...

A U.S. professor says she is unconvinced new technologies such as functional magnetic resonance imaging are superior to polygraph tests for detecting lies. University of Illinois Professor Melissa Littlefield says in today's forensically sophisticated, CSI-influenced world, polygraphy -- which bases its results on functions of the autonomic nervous system -- is being increasingly dismissed as dated and unreliable. Functional magnetic resonance imaging and Brain Fingerprinting have been hailed...

 When a crime has been committed, the usual modus operandi for police detectives and their fictional counterparts has been to dust the scene for fingerprints. And once they have a suspect in custody, out comes the polygraph, or lie detector.But in today's forensically sophisticated, "CSI"-influenced world, polygraphy "“ which bases its results on functions of the autonomic nervous system "“ is increasingly dismissed as dated and unreliable. Rapidly replacing older...

Portions of the brain that activate when people view pictures of objects compared to scrambled images can also be activated by touch alone, confirms a new report published online on May 28th in Current Biology, a Cell Press publication. "That's the nub of the paper," said Harriet Allen of the University of Birmingham. "Part of the brain is for object processing irrespective of the sensory input coming in." The discovery was made by studying a man, known as HJA, with a condition called visual...

A new study demonstrates that when faced with a difficult decision, the human brain calls upon multiple neural systems that code for different sorts of behaviors and strategies. The research, published by Cell Press in the May 28th issue of the journal Neuron, provides intriguing insight into the mechanisms that help the human brain rise to the formidable challenge of adaptive decision making in the real world."When faced with a complex decision, many individuals engage in simplifying...
