Sulpiride, but not SCH23390, modifies cocaine-induced conditioned place preference and expression of tyrosine hydroxylase and elongation factor 1α in zebrafish

► We describe a new conditioned place preference (CPP) assay used for zebrafish. ► We describe the impact of dopamine antagonists on CPP. ► We show gene expression changes in the telencephalon that correspond with CPP. ► EF1α is lowered in the ventral telencephalon of cocaine-treated fish.
