Serotonin 1B receptors (5-HT1BRs) are a novel target for developing pharmacological therapies to reduce psychostimulant craving. 5-HT1BRs are expressed in the mesolimbic pathway projecting from the ventral tegmental area (VTA) to the nucleus accumbens (NAc), which is involved in reward and motivation. 5-HT1BR agonists modulate both cocaine- and methamphetamine-seeking behaviors in rat models of psychostimulant craving. In this dissertation, I tested the central hypothesis that 5-HT1BRs regulate cocaine and methamphetamine stimulant and rewarding effects in mice.
