Habituation 4.45 (0.56) 4.25 (0.67)
Conditioning 2.33 (0.40)† 3.11 (0.66)
Extinction 6.55 (1.26) 4.10 (0.48)
Extinction Retrieval 3.30 (0.30)‡ 3.00 (0.37)
Prelimbic Cortex
Training Phase Unstressed Stressed
Habituation 3.56 (0.39) 3.18 (0.44)
Conditioning 1.88 (0.31)† 1.22 (0.21)†
Extinction 3.87 (0.45) 2.07 (0.21)*§
Extinction Retrieval 2.85 (0.34) 2.96 (0.46)

Asterisk (*), significant difference relative to unstressed within a training phase and brain region;

dagger (†), significant difference relative to habituation, initial extinction, and extinction retrieval within a treatment group and brain region;

double dagger (‡), significant difference relative to habituation and initial extinction within a treatment group and brain region;

section sign (§), significant difference relative to habituation within a treatment group and brain region
