BOB HIRSHON (host):

Watching addiction unfold. I’m Bob Hirshon and this is Science Update.

How drugs cause addiction is poorly understood. At a meeting of the American Chemical Society, neuroscientist Paul Slesinger, from the Icahn School of Medicine at Mount Sinai, reports using brain implants that light up in the presence of addiction-related brain chemicals, like dopamine and norephinephrine.

PAUL SLESINGER (Icahn School of Medicine at Mount Sinai):

And what we were looking at was the release of these neurotransmitters in living mice, where the mice are learning to pair a reward with a tone that they hear that precedes the reward.

HIRSHON:

They’re correlating the timing of a neurotransmitter’s release with its effects on particular neurons, as the mice learn to anticipate a reward. Slesinger says that will help them better understand the chemistry of addiction, and perhaps identify methods to prevent it. I’m Bob Hirshon, for AAAS, the science society.
