A study conducted by Dr. Ana Rose Childress and Dr. Charles O’Brien of the University of Pennsylvania shows drug craving “triggers” are activated in the part of the brain responsible for emotions and rewards.
Cocaine addicts were shown a series of images for 33 milliseconds each—not nearly enough time to register consciously—yet brain imaging of the study participants showed activity in the limbic system (the area of the brain that is directly associated with reward) that coincided with the images.
“[The study] is the first evidence that cues outside one’s awareness can trigger rapid activation of the circuits driving drug-seeking behavior.”
-Dr. Ana Rose Childress
