Learning ability in the pairwise visual discrimination test and spatial memory in object location test and object recognition memory test. There was no difference in the percentage of correct answer between groups for nine days performance (A). Long-term spatial memory was disrupted in PFOS-exposed mice in object location test (B). Object recognition memory was not impaired in PFOS-exposed mice (C). Data are expressed as the mean \(\pm\) SEM. n = 9 mice in each group
