Serotonin receptors mediate the effect of amphetamine. A, Time course data from five cells (open symbols) illustrating that the effect of amphetamine is almost completely blocked in the presence of methysergide (10 μm) compared with control data (filled symbols; from Fig. 3A). Four of five cells were dopamine cells. B, Time course data from five cells (open symbols) showing that the effect of amphetamine is inhibited in the presence of methiothepin (1 μm) compared with control data (filled symbols; from Fig. 3A). Four of five cells were dopamine cells.
