Statistical analysis
All data were analyzed using GraphPad prism version 7.0 and presented as
mean ± SEM. For two groups, unpaired Student’s t test was
applied. For multiple groups, One-way ANOVA was used. In addition,
two-way ANOVA was used to analyze data of the time spent with the object
in the novel object recognition test. P < 0.05 was
considered statistically significant.
