1B ), unlike control mice ( t 12 = 9.957, p < 0.0001, n = 13, one-sample t test), mice in the ELS group only showed a trend to discriminate the displaced object from the non-displaced one ( t 10 = 2.053, p = 0.067, n = 11, one-sample t test) and exhibited significantly lower preference index than the CT group ( t 22 = 2.522, p = 0.019; unpaired t test), indicating that ELS induces spatial memory deficits.
