Battery Powered Brain

CNN's Dr. Sanjay Gupta tells the story of a severely depressed patient, who
underwent an experimental surgery in which doctors drilled two
holes in her skull to implant a pair of battery-powered electrodes in her

A small electrical charge then stimulates a part of the brain known
as ³Area 25,² which is a junction box for the circuits that control our
moods. The patients who undergo this procedure have not been helped by
anything else. Not psychotherapy; not meds; not even electro-convulsive
shock therapy. But about two-thirds of the experimental subjects using Deep
Brain Stimulation have improved significantly.

Battery Powered Brain is one of three in-depth stories in one riveting hour hosted
by CNN's Randi Kaye and Drew Griffin. CNN Presents premieres an all-new show tonight at 8pm ET, re-airing at 11:00 pm and 2:00 am ET.

The Scary Guy

He's a former tattoo artist who commands tens of thousands of dollars to speak to schoolchildren worldwide in the name of bullying prevention. While his tattooed face and outrageous tactics may capture the hearts and minds of kids, critics question whether he has a lasting impact.

CNN's Randi Kaye visits two Minnesota schools – one hoping the twenty thousand dollars the community paid Scary will help them solve the bullying problem, the other going a different route after a Scary experience.

The Scary Guy re-airs on CNN Presents this Saturday at 8:00 pm ET, 11:00 pm and 2:00 am ET.
