Table 1.

Sleep parameters in larval zebrafish. Group 1, control; Group 2, group exposed for 24 h to VPA; Group 3, group exposed for 48 h to VPA; and Group 4, group exposed for 72 h to VPA. The experimental groups were compared to control group and the results are represented as average ± SEM; p < 0.05 was considered to be significant, MANOVA and Bonferroni analysis; N.S., not significant results.
