The (A) mean total swim distance, (B) latency to the correct zone, (C) time in the correct zone, (D) % of total swim distance in the correct zone and (E) % entries to the correct zone of female BALB/C mice (N=30) on standard diet administered 0.9% saline (n=10), standard diet administered cyclophosphamide (CYP) and doxorubicin (DOX) or 2% choline diet administered DOX+CYP was determined weekly during probe trials. Data are presented as group means +/− S.E.M. Using Dunnett’s test, signifcant (p<0.05) differences from baseline (day 15) performance are indicated with a *. Using Tukey’s HSD, signifcant (p<0.05) differences from the Standard Diet – Saline group are indicated with † and differences from Choline Diet (2%) – DOX+CYP group are indicated with •.
