ERD plots of C3 and C4 during left and right hand imagery movements from subject 9’s offline data. These plots illustrate the spectral power change versus time during imagery compared to the reference interval. Notice the power decease in C4 during left hand imagery (a), and the power decrease in C3 during right hand imagery (b)
