Results of behavioral tests of progenies. a, b Results of open-field test at 7 weeks of age. a Locomotor activity patterns during the open-field test at 7 weeks of age. b Time spent in the center (30% of the open-field arena) at 7 weeks of age. c, d Results of object-exploration test. c Time spent exploring a novel object. d Number of times mice that made contact with a novel object. e, f Results of social-interaction test. e Time spent exploring a novel mouse. Number of subjects: CD, 9; PR, 10; FA, 7. f Number of times mice made contact with a novel mouse. g–i Locomotor activity of mice in their home cages. g Mean locomotor activity during the light period. h Mean locomotor activity in the home cage during the dark period. i Locomotor activity in the home cage during the light/dark cycle. a–i Number of subjects: CD, 10; PR, 10; FA, 7. Data represent the mean ± SEM. Asterisks indicate significant differences between groups in post hoc analyses (Fisher’s PLSD test, *: P < 0.05)
