Time course of psychostimulants on dopamine transmission across 30 minutes (post-injection) as measured by A) peak height, upward velocity (inset), B) ratio of upward velocity to peak height, C) exponential decay (tau), and E) downward velocity for WF23 (black), PTT (purple), and cocaine (pink). All values normalized to baseline. D) Comparison of tau (normalized) to ratio of upward velocity to peak height for each drug across the full time course. F) Comparison of downward velocity (normalized) to tau (normalized) for each drug.
