Tests on amphetamine-addicted laboratory rats showed that when the insular cortex was deactivated by injecting a drug that halted brain cell activity, the rats showed no signs of addiction.
When the insular cortex was reactivated, the rats again showed signs of craving amphetamines, according to the research to be published in Friday's edition of the journal Science.
