EEG Signals Analysis Using Multiscale Entropy for Depth of Anesthesia Monitoring during Surgery through Artificial Neural Networks

Figure 8

Statistical analysis of MSE from ten patients’ EEG under different states at multiple time scales. Stage 1 is preoperation and stage 3 is maintenance during surgery. Symbols marked with “” indicate significant difference between stage 1 and stage 3 with . (a) Before filtering. (b) After filtering.
