PHILADELPHIA (KYW Newsradio) — There are many things we can be addicted to: We can be addicted to cigarettes, gambling, cocaine and narcotics, to name just a few.

Researchers are always looking at ways to deal with this. Scientists at the University of California  think they may one day be able to zap brain cells to stop addictive cocaine-seeking behavior — at least that's what their landmark study in rats suggested. 

The scientists modified brain cells in rats to make them susceptible to activation and deactivation by laser light, and "light on" activation eliminated compulsive cocaine seeking behavior. 

While this isn't being used in humans, the technique might also be able to be used in our brains, using electromagnetic fields generated outside the scalp.
