Brain Treatments
Head Lines | Mind & Brain [image: Cover Image: March 2013 Scientific American Magazine]See Inside Old Drugs Find New Life as Brain Treatments By Daisy Yuhas | March 21, 2013 | 1 - Share - Email Developing new drugs is no easy feat. As much as 95 percent of new compounds fail along the path to becoming clinically available. Attrition is especially high for drugs treating the central nervous system. The ones that do succeed rack up an average cost of $1.8 billion. So researchers are increasingly turning to the bottles already on the shelf. Proved safe for human consumption an... mais »

Brain Activity
Full-brain waves challenge area-specific view of brain activityMarch 21, 2013 *[+]* A still-shot of a wave of brain activity measured by electrical signals in the outside (left view) and inside (right view) surface of the brain. The color scale shows the peak of the wave as hot colors and the trough as dark colors. (Credit: David Alexander/KU Leuven) Our understanding of brain activity has traditionally been linked to brain areas — when we speak, the speech area of the brain is active. New research by an international team of psychologistsshows that this view may be wrong. The entire...mais »
