Summary of behavioral data obtained from the experiment presented in Figure 1.

Group	Starting phase (mean ± SEM)	Number of mice
I	14.17 ± 0.59	10
II	16.09 ± 0.59	12
III	15.86 ± 0.56	13
IV	14.40 ± 0.65	11
Total	15.19 ± 0.32	46

A total of 46 mice were used in four independent experiments. The extrapolated starting phase of each group in the 2nd DD is presented as mean ± SEM. The starting phases among the groups were not significantly different by ANOVA (F = 2.783; p = 0.53).
