Unraveling the brain’s reward circuits: Food, alcohol, and certain drugs all act to reduce the activity of hunger neurons and to release reward signals in the brain.

But alcohol and drugs rely on a different pathway than does food, according to a new study. The findings could point researchers to new strategies to design weight-loss or anti-addiction drugs. To some, a chocolate cake may spark a shot of pleasure typically associated with illicit drugs. A new study by Penn biologists offers some insights into that link, revealing new information about how the brain responds to rewards such as food and drugs.
