CINCINNATI, June 15 /PRNewswire-FirstCall/ -- Kendle (Nasdaq: KNDL), a leading, global full-service clinical research organization, today announced it now offers Brain Network Activation (BNA) imaging providing a non-invasive platform for mapping, monitoring and understanding brain electro-physiological network activity in response to cognitive or physiological stimuli. The BNA imaging technology was developed by ElMindA, a medical technology development company based in Herzliya, Israel....

There are biological motivations behind the stereotypically poor decisions and risky behavior associated with adolescence, new research from a University of Texas at Austin psychologist reveals. Previous studies have found that teenagers tend to be more sensitive to rewards than either children or adults. Now, Russell Poldrack and fellow researchers have taken the first major step in identifying which brain systems cause adolescents to have these urges and what implications these biological...

Researchers at Harvard-affiliated McLean Hospital have produced the first evidence that the opioid blocker extended-release injectable naltrexone (XR-NTX) is able to reduce the brain's response to cues that may cause alcoholics to relapse. In data presented today at the annual meeting of the American Psychiatric Association, Scott Lukas, PhD, director of the Neuroimaging Center at McLean, located in Belmont, Mass., said the findings help in the understanding of how XR-NTX works in reducing...

Like a motorist who knows that the "check engine" light indicates something important but ill-defined is happening, neuroscientists have relied heavily on an incompletely understood technology called functional magnetic resonance imaging to show them what the brain is doing when people respond to different stimuli. The non-invasive technology offers a window into the physiology of human cognition and emotion, but "” without a satisfying explanation of how some common fMRI signals are...

By reading MRI scans, new software developed by Intel Corp. researchers has been able to correctly discern two words that a person has been thinking about nine out of 10 times, according to an Associated Press (AP) report published Thursday. According to AP writer Samantha Gross, "The software analyzes functional MRI scans to determine what parts of a person's brain is being activated as he or she thinks"¦ Eventually, the technology could help the severely physically disabled to...

Changes in brain connectivity with aging may enable older adults to remember positive events Milan, Italy -- Despite the aches and pains that occur in old age, many older adults maintain a positive outlook, remembering the positive experiences from their past. A new study, reported in the April 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex), reveals that older adults' ability to remember the past through a positive lens is linked to the way in which the brain...

Clinicians may be able to better predict the effects of strokes and other brain injuries by adapting a scanning approach originally developed for study of brain organization, neurologists at Washington University School of Medicine in St. Louis have found. The technique, known as resting-state functional connectivity (FC), reveals the health of brain networks that let multiple parts of the brain collaborate. Previous studies have shown that damage to these networks helps explain why damage to...

The more difficult the decision we face, the more likely we are not to act, according to new research by UCL scientists that examines the neural pathways involved in 'status quo bias' in the human brain. The study, published today in Proceedings of the National Academy of Sciences (PNAS), looked at the decision-making of participants taking part in a tennis 'line judgement' game while their brains were scanned using functional MRI (fMRI). First author Stephen Fleming, Wellcome Trust Centre...

It's no wonder attractive human faces are everywhere in media and advertising "“ when we see those faces, our brains are constantly computing how much the experiences are worth to us. New brain-imaging research shows it's even possible to predict how much people might be willing to pay for a particular face. Researchers at Duke University Medical Center found that as participants were watching a sequence of faces, their brains were simultaneously evaluating those faces in two distinct...

A study by British and Belgian researchers found that a man who had been presumed to be in a vegetative state for five years, can communicate "yes" and "no" using only his thought patterns, Reuters reported. The researchers said the man sustained a severe traumatic brain injury in a traffic accident in 2003. He remained physically unresponsive and was presumed to be in a vegetative state for five years. The study results, published in the authoritative New England Journal of Medicine, said...
