Cocaine infusions earned before and during the dose-response challenge

This data set represents the number of cocaine infusions each subject earned for the last two days preceding (2a), and for the two consecutive sessions during (2b), the dose-response challenge for mice of each genotype. TRPC5 +/+ = wild-type; TRPC5 -/- = knock-down; "-2" = second to last day leading up to dose-response challenge; "-1" = last day leading up to dose-response challenge; S(0.05) = session with dose 0.05 mg/kg/infusion; S(0.1) = session with dose 0.1 mg/kg/infusion; S(0.75) = session with dose 0.75 mg/kg/infusion; S(2.0) = session with does 2.0 mg/kg/infusion; S1 = first daily session with respective dose; S2 = second daily session with respective dose
