Correlation of frontal lobe electroencephalogram asymmetry and cognitive prognosis in schizophrenia

Figure 1 Comparison of asymmetry of electroencephalography. A and B: In lateral prefrontal cortex between two groups. The frontal alpha asymmetry (FAA) values were calculated using the difference in alpha power between right (F4) and left (F3) frontal regions; C and D: In anterior temporal region between two groups. The FAA values were calculated using the difference in alpha power between right (F8) and left (F7) frontal regions; E and F: In frontal lobe between two groups. The FAA values were calculated using the difference in alpha power between right (FP2) and left (FP1) frontal regions; G and H: In medial prefrontal cortex between two groups. The FAA values were calculated using the difference in alpha power between right (AF4) and left (AF3) frontal regions; I and J: In middle frontal gyrus between two groups. The FAA values were calculated using the difference in alpha power between right (F6) and left (F5) frontal regions; K and L: In prefrontal cortex between two groups. The FAA values were calculated using the difference in alpha power between right (F2) and left (F1) frontal regions. Statistical comparisons were performed using independent samples t-tests. FAA: Frontal alpha asymmetry; NS: No statistically significant difference. ^aP < 0.05.
