Behavioral effects of cuprizone and quetiapine treatment. (A) The cuprizone-treated mice had an inferior prepulse inhibition (PPI), which was reversed by quetiapine treatment (main effect of treatment, F 3, 92=3.835, P=.013). (B-C) The cuprizone-treated mice spent less time (F 3, 20=4.886, P<.05), travelled a shorter distance (F 3, 18=4.212, P<.05) in the central area of the open field test, and exhibited anxiety-like behaviors, which were ameliorated by quetiapine cotreatment. (D) In the Y-maze test, cuprizone-treated mice showed impaired spatial working memory and spatial cognitive ability, which was rescued by quetiapine administration (F 3, 25=3.114, P<.05). (E-F) In the 3-chamber test, mice in the cuprizone group showed reduced social interactions and weaker social memory. Mice in the cuprizone + quetiapine group performed better than those treated with cuprizone alone. #P<.05 compared with the control group or the CPZ + Que group; *P<.05, **P<.01, + P<.05, ++ P<.01, compared with the empty wire cup or Stranger 1.
