[A] Time-frequency plots (average data) of the difference between the conditions where the pre-cue did or did not specify Individual Action (Left) or Joint Configuration (Right). For both factors the difference in alpha suppression (in blue) becomes evident around 400 ms before the onset of the Go cue. [B] Amplitude of alpha/mu rhythm during the last 400 ms before Go onset (average data). [C] Scalp topographies of alpha/mu distribution: Average (Avg) of all conditions and Lateralization of alpha activity before Go onset, created by subtracting the activity of the ipsilateral hemisphere from that of the contralateral hemisphere separately for each hand and then averaging the two differences.
