Figure 1: Burying latency. A volume of 1 mL of the artificial FAT mixture and diazepam (2.0 mg/kg) significantly ( , SNK post hoc test) increased burying latency compared with vehicle and the 0.125 and 0.25 mL artificial FAT mixture groups. The data points of the dose-response curve were fit to a logarithmic curve . FAT, fatty acid; VEH, vehicle of fatty acid mixture; DZP, diazepam.
