Model for OCT3-dependent amphetamine-evoked DA release. Cartoon depicting proposed mechanisms of action of amphetamine based on present results. Amphetamine enters neurons via DAT or diffusion across the plasma membrane “A”. Once inside, amphetamine causes release of DA via reverse transport through DAT “B” and OCT3 “C”
