Effects of stress on neural processing of combat-related stimuli in deployed soldiers: an fMRI study.

Additionally, we tested for significant group differences in correlations in amygdala and hippocampus using one-sided Z -tests (according to https://www.psychometrica.de/correlation.html#independent ) and found significant differences between the correlations of the two groups in left amygdala ( Z = 2.243; p = 0.012) and right hippocampus ( Z = 1.697; p = 0.045), while the difference in the left hippocampus was only almost significant ( Z = 1.525; p = 0.064) and in right amygdala not significant ( Z = 1.172; p = 0.121).
