Latency to find a hidden platform is similar in all males (a) and all females (a) across the 8 days of learning. When mice were tested on Day 9 for memory of the platform location in a 60 sec probe trial, both male (c) and female (d) wildtype folate deficient (WTFD) showed impairments. All values are average ± SEM. n's per group are given in parenthesis next to each experimental group; * signifies p < 0.05 between Q1 and Q2 – Q4. † signifies p < 0.05 between Q1 and Q2 – Q3, but not Q4. ‡ p < 0.05. Abbreviations: WTC, wildtype control; WTFD, wildtype folate deficient; GC, GCPII+/- control; GFD, GCPII+/- folate deficient.
