If you missed the Nov. 24 episode of MTV Live that was hosted in senior Natasha Lazo's dorm room in the Homewood Apartments, you'll have a chance to see JHU undergrads participating live on Tuesday, Dec. 9. And now that the line is installed, the network plans to revisit the Homewood campus for future shows. It's medical education for the electronic age. Internet users can now sit in on Hopkins' Medical Grand Rounds, a 40-year tradition whose sessions have ranged from weight loss in elderly men and the complications of prosthetic heart valves to pancreatic cancer and advances in the treatment of Wegener's granulomatosis. The Internet audience can listen to the live presentation, view illustrative slides and submit questions by e-mail.

Dopamine's activity appeared to increase two to three times over baseline levels in the brain area studied, the putamen, compared to a control area, the cerebellum. Improvements in scanning technology eventually may track cocaine's effects on the dopamine-generating nucleus accumbens, a smaller area nearby in the brain that is known to play a role in addictive behavior in animals, adds Godfrey Pearlson, professor of psychiatry and a lead author on the paper. The study was published in the September issue of the American Journal of Psychiatry. Other authors were Dean Wong, Stefano Marenco and Robert Dannals.
