Abstract The effects of food deprivation (24 h) on response rates of rats self-administering d-amphetamine and cocaine were compared. Food deprivation clearly increased rates of responding for both drugs but did so to a significantly greater extent for cocaine than for d-amphetamine. Consistent with other findings, the results suggest that the neural substrates underlying cocaine and d-amphetamine reinforcement are not identical.
