Suppression of PR performance following systemic raclopride administration. a Breakpoint values of C57Bl/6 mice (n = 18) administered 0.03 or 0.3 mg/kg raclopride versus vehicle. b–c Raclopride differentially affects reward collection latency and post reinforcement pause. d–f Effect of raclopride on the rate of IR beam breaks in the behavioural arena and magazine. g Effect of raclopride on the rate of responding at non-target touchscreen locations. h Effects of raclopride on total response time across multiple response requirements. i Effects of raclopride on inter-response interval across multiple response requirements (*p < 0.05; #p < 0.08; ns not significant)
