Correlation between HAMD scores and smFC activity of the MDD patients. The HAMD scores of the MDD patients were negatively correlated with the GBAI of the left superior medial frontal cortex (r = −0.529, P = 0.009 at 35 ms). HAMD: Hamilton Depression Rating Scale; MDD: major depressive disorder; GBAI: gamma-band activation index; smFC: superior medial frontal cortex.

Figure 1. From: Abnormal Early Gamma Responses to Emotional Faces Differentiate Unipolar from Bipolar Disorder Patients.

Abnormal regional activity of the MDD patients in early emotion perception at peak time points. Decreased (a) and increased activity (b) in the MDD patients. MDD: major depressive disorder; NC: normal control; AI: anterior insula; OFC: orbitofrontal cortex; TP: temporal pole; PHC: parahippocampus; smFC: superior medial frontal cortex.

The scatterplots showed individual discriminant function scores of the MDD and BD patients. The black bars illustrated the patient group means. The stepwise discriminant analysis identified four abnormal regional GBAIs of the most discriminating from the MDD (blue circle) and BD (red star) patients (F4,43 = 9.77, P < 0.0001) and the function scores were significantly different (t47 = 20.87, P < 0.0001). The two BD patients (black circle) were initially diagnosed as the MDD patients. The four abnormal regions include the left superior medial frontal cortex (happy 35 ms), the right medial orbitofrontal cortex (happy 35 ms), the right anterior insula/inferior orbitofrontal cortex (sad 60 ms), and the right precentral cortex (sad 105 ms). MDD: major depressive disorder; BD: bipolar disorder; GBAI: gamma-band activation index.
