Movement Type Prediction before Its Onset Using Signals from Prefrontal Area: An Electrocorticography Study

Figure 2

Frequency ranges of each subject’s selected electrodes located in the primary sensorimotor, premotor and supplementary motor (Brodmann area 6), and prefrontal areas. The frequencies were divided into the delta, theta, alpha, beta, and gamma brain waves. The predominant frequency range was in the beta band (13–30 Hz). S: subject.
