Figure 1.

Mean (± standard error mean, SE) values of the event-related lagged linear connectivity (ErLLC) of subdural electrocorticographic (ECoG) rhythms for two pairs of cortical region of interest (ROI; i.e., BA1/2/4 and BA6 pair; BA6 and BA44/45 pair). The ErLLC values refer to four ECoG frequency bands of interest (i.e., delta-theta, alpha, beta, gamma) and two experimental conditions (i.e., EXECUTION, OBSERVATION). Noteworthy, the only significant t-test effect was that the delta-theta ErLLC in the BA6 and BA44/45 pair was greater during the EXECUTION than the OBSERVATION condition (t = 2.26; p = 0.04; one-tailed).
