In a study on rodents, investigators from the National Institute on Drug Abuse used tracers to confirm that the reward pathways started with glutamate cells in the dorsal raphe nucleus, which connect to dopamine cells in the ventral tegmental area, which eventually lead to the nucleus accumbens, a brain structure important to reward, pleasure, and motivation.
