Fig 2. Nose poking and initial fear discrimination.

(A) Mean ± SEM baseline nose poke rates throughout initial fear discrimination are shown for sham (gray) and lOFC rats (black). Mean ± SEM suppression ratio for danger (red), uncertainty (purple) and safety (blue) are shown for (B) sham and (C) lOFC rats for initial fear discrimination. Vertical line separates the two pre-exposure sessions (P₁ and P₂), from fear discrimination for each graph.
