To compare the response to rewards (drug and non-drug related) in cocaine dependent and non- dependent individuals and study the effect of expectation on reward-related (both drug and non-drug induced) subjective responses and neuronal activity.
To compare visual and olfactory cues as they relate to receipt of a non-drug reward. Olfactory cues follow a more direct path into the limbic system and thus, may alter reward system functioning differently than do visual cues.
