A – Effects of voluntary water or 0.30 mg/mL MDPV solution consumption on place conditioning after 21-hour fluid deprivation. Abscissa: Fluids paired with each side of the two conditioning compartments. Ordinate: Change in time spent in the relevant conditioning compartment during the post-conditioning test. Asterisk indicates significant difference between water-conditioned and MDPV-conditioned groups. B – Effects of IP-administered MDPV on place conditioning. Abscissa: Doses of MDPV paired with each side of the two conditioning compartments. Ordinate: Change in time spent in the relevant conditioning compartment during the post-conditioning test. Asterisk indicates significant difference between saline-conditioned and MDPV-conditioned groups.
