Frontal EEG Temporal and Spectral Dynamics Similarity Analysis between Propofol and Desflurane Induced Anesthesia Using Hilbert-Huang Transform

Table 1

Frequency band power distribution variation. Standard deviation (std) of power within each frequency band is calculated for every case among both methods and then all the standard deviation values in a specific group are statistically shown as mean ± std.
