"OR Live" invites you inside the operating room (the "O.R." )to see real brain surgery. The site currently has videos showing operations for a brain aneurysm, spinal cord problems, brain tumor, epilepsy (temporal lobectomy), and deep brain stimulation for Parkinson's disease. Just select the operation you want to watch from the long list on the site. The videos are available in "Real Player" and/or "Windows Media" formats.
CAUTION: "OR LIVE" is not for the squeamish! The videos show actual
surgery being performed.
For the Neuroscience Research Prize, three winners will each receive a $1,000 cash prize and an all-expense paid trip to present their projects at the Annual Meeting of the American Academy of Neurology (Boston, MA; April 28 - May 5, 2007). One additional winner will receive a $1,000 cash prize and all-expense paid trip to present his/her project at the Annual Meeting of the Child Neurology Society (Quebec City, Quebec, Canada; October 10 - October 13, 2007). Winners' teachers are also invited to the Annual Meeting, all expenses paid. Certificates are awarded during the Annual Meeting Awards Luncheon. To apply for the Neuroscience Research Prize go to:
For the Neuroscience Creativity Prize, five winners will each receive $100 and a $100 gift card for neuroscience books. Five finalists will each receive a $100 gift card for neuroscience books. To apply for the Neuroscience Creativity prize go to:

Dr. Stevens built life-sized heads of dinosaurs to estimate the visual abilities of these extinct animals. He estimates that T. rex had excellent depth perception because this dinosaur had a large binocular range (the visual field that is overlapped by two eyes). T. rex also had huge eyes with diameters of 91 to 119 mm (~4 inches). By comparison, human eyes have a diameter of only 24.5 mm (~1 inch). Dr. Stevens calculates that T. rex could see distinct objects from a distance of 6 kilometers (~3.5 miles). By comparison, humans can see distinct objects from a maximum distance of only 1.6 km (1 mile). The visual acuity of T. rex vision is as much as 13 times better than that of people.
These data suggest that T. rex was not a scavenger as many scientists believe. Rather, with its excellent visual abilities, T. rex was likely a skillful hunter.
