(A) No group differences were detected between Hetero-KO mice and their Controls in the total exploration (i) or percentage exploration of the center (ii) of the open field, (n=32). (B) No group differences were detected between Hetero-KO mice and their Controls in total exploration (i), percentage exploration of the light, (ii), or entries into the light (iii) in the light/dark choice test, (n=41). (C) No group differences were detected between Adult-Hetero-KO mice and their Controls in the total exploration (i) or percentage exploration of the center (ii) of the open field, (n=47). (D) No group differences were detected between Adult-Hetero-KO mice and their Controls in total exploration (i), percentage exploration of the light, (ii), or entries into the light (iii) in the light/dark choice test, (n=30). (E) Auto-KO mice displayed decreased total exploration (i) and decreased percentage exploration of the center (ii) of the open field, compared to their Controls, (n=50). (F) Auto-KO mice displayed less total exploration (i) and fewer entries into the light compartment (iii), but no difference in percentage exploration of the light (ii) compared to their Controls in the light/dark choice test, (n=37). All values are mean ± SEM. *p<0.05, **p<0.01, ***p<0.001.
