Assessment of general locomotor activity of D1–CB1−/− mice in the open field (OF) test. Conditional D1–CB1−/− mutant mice (KO) and their respective wild-type (WT) littermates were tested in an open field for 30 min. Values are mean ± SEM in terms of locomotor activity (A–D) rearing (E) and jumping episodes (F).
