"The Beautiful Mind" is a photo exhibition developed by the Cooperation in Research and Training for European Excellence in the Neurosciences. The exhibit will tour in 2009 and reach London, Berlin, Zurich, Stockholm, Prague, Oslo, Helsinki and Bochum.
Navigation through the photographs on the Web site takes a bit of practice. The images are organized into six sections - Generation, Memory, Maze, Coupling, Nova and Peacock field - but it is unclear why these sections are named this way or why the selected photos have been placed in each section. To see the photos, click on one of the boxes in the upper left corner of the screen. This will display a column of small photos on the right side. To enlarge one of the small photos, just click on one. If you want to find out more about each picture, move your mouse over the image. You can scroll down the column of small images to see more photos.
The site would be more useful if additional details about each photograph
were given. Nevertheless, the site provides some fascinating, beautiful
images of the cells that make up your brain.
The non-profit Sports Legacy Institute (SLI) was established in 2007 to study the long-term effects of head injuries in sports. Led by its founding members Christopher Nowinski (a former professional wrestler) and Dr. Robert Cantu (a neurosurgeon at Emerson Hospital), the SLI mission is "to advance the health and wellness of athletes and the overall safety of sports and athletic endeavors." The initial focus of the SLI has been to study concussions.
One program the SLI has started is the collection and analysis of the brains of professional athletes. So far, several National Football League players have agreed to donate their brains to the SLI after they die. Most recently, former National Hockey League center, Keith Primeau, has joined this group. The SLI hopes the study of brains from athletes who have suffered concussions will provide useful information about how the brain reacts to injury and about how to prevent and treat such injuries.
Did you know? SLI founding member Christopher Nowinski ended his career as a professional wrestler when he suffered a concussion in 2003.
