Regional differences in the BOLD response to masked-sad faces versus masked-neutral faces (SN-NN) and masked-happy versus masked-neutral faces (HN-NN) in patients with major depressive disorder and healthy controls.

Abbreviations: L = left; R = right; MDD = major depressive disorder; HC = healthy control; SN = masked-sad faces; HN = masked-happy faces; NN = masked-neutral faces; SN-NN = masked-sad versus masked-neutral faces; HN-NN = masked-happy versus masked-neutral faces; STG = superior temporal gyrus; OFC = orbitofrontal cortex; C = cortex; ACC = anterior cingulate cortex; G = gyrus; PFC = prefrontal cortex.
*The cluster size was significant after applying a cluster threshold of k = 23 voxels using Monte Carlo simulations implemented in AFNI's AlphaSim program to correct for multiple comparisons.
#The statistical t-values for these regions are reported in the text, while corresponding z-values are reported in the table.
