Changes at glutamate tripartite synapses in the prefrontal cortex of a new animal model of resilience/vulnerability to acute stress.

However, when FS-R and FS-V animals were segregated 24 h after stress as above, we observed that FS-V rats showed a trend for reduced sucrose intake compared to both CNT and FS-R animals already 6 h after stress while the reduction was significant 24 h and 72 h after FS (significant effect of time F(4,81) = 6.762 and stress F(2,22) = 10.54; Tukey’s test: 6 h: FS-V vs CNT p = 0.0592, FS-V vs FS-R p = 0.0727; 24 h: FS-V vs CNT p < 0.01, FS-V vs FS-R p < 0.01; 72 h: FS-V vs CNT p < 0.05, FS-V vs FS-R p < 0.05) (Fig. 2C ).
