Figure 1: Defensive burying test. (a) Burying latency was significantly longer in the FAT-M group pretreated with vehicle-1, an effect attenuated by pretreatment with GABAA antagonists. (b) Cumulative burying time was significantly shorter in the vehicle-1 + FAT-M, bicuculline + FAT-M, and flumazenil + FAT-M groups than in the vehicle-1 + vehicle-2, an effect not detected in the picrotoxin + FAT-M group ( , Student-Newman-Keuls post hoc test). FAT-M, fatty acid mixture.
