Stress effects on brain activity and connectivity. A, The right caudate nucleus was significantly more activated in the stress compared with the control group (pFWE < 0.05). B, C, Functional connectivity between the left amygdala and the hippocampus was decreased after stress (pFWE < 0.05), whereas functional connectivity between amygdala and putamen tended to increase after stress (pFWE = 0.063). Activations are superimposed on coronal and sagittal axial sections of a T1-weighted template image (red). Blue represents anatomical masks. L, Left side of the brain; R, right side of the brain. Error bars indicate SEM.
