Frontal Alpha Complexity of Different Severity Depression Patients

Figure 2

Complexity distribution among different depression severities and healthy controls. Each panel shows one of the six features distribution among four groups: (a)–(c) sample entropy of Fp1, Fz, and Fp2 poles, (d)–(f) Lempel–Ziv complexity of three poles. The mean feature value of each group is shown by the height of the bar, while the standard error shown by the length of the horizontal bar exceeding the main bar. “”: significant difference with  < 0.05. “”: significant difference with  < 0.01.
