Comparison between oscillatory properties in alpha band. (A) Raw power spectrum (black circles) and its aperiodic activity (yellow line) and periodic activity (orange line) in eyes-open state in an example subject. (B) Raw power spectrum (black circles) and its aperiodic activity (yellow line) and periodic activity (orange line) in eyes-closed state in an example subject shown in (A). (C) Periodic activity (orange line) in eyes-open and eyes-closed states in an example subject shown in A and (B) (D) Distribution of alpha peak numbers in eyes-open (white) and eyes-closed (black) states. (E) Comparison of peak frequencies of periodic activities in alpha band in eyes-open and eyes-closed states. (F) Comparison of bandwidths of periodic activities in alpha band in eyes-open and eyes-closed states. .
