Group-level spatial distribution of alpha power. (A) Alpha oscillations can be observed during the baseline-awake state. (B) Lack of response during sevoflurane anesthesia effect-onset was associated with decreased awake-alpha oscillations compared to response. (C) Large amplitude frontal alpha-oscillations were observed with sevoflurane general anesthesia (GA). (D) Lack of response during sevoflurane anesthesia effect-offset was associated with decreased awake-alpha oscillations compared to response.
