Is neuroticism really bad for you? Dynamics in personality and limbic reactivity prior to, during and following real-life combat stress.

Elevated neuroticism during military service was associated with reduced hippocampal activation at that time relative to oneself, while the association between elevated neuroticism following discharge and increased hippocampal activation was trending towards significance (B (tp2) = −12.64, p = .005, 95% CI -21.47 to −3.81; B (tp3) = 11.69, p = .061, 95% CI -0.54 to −23.92, respectively; Fig. 3C ).
