Cross-PAC dynamics in two blocks of oddball experiments for channel pairs: (a) Fz (amplitude)-F3 (phase), (b) Pz (amplitude)-F3 (phase). Blue lines show averages over subjects and light margins indicate ± std/2 over subjects. It can be seen that the cross-PAC peak in the frontal region (Fz-F3) occurs earlier in the second block for the CTL and PD OFF groups, but not for the PD ON group. No advancement of the peak occurs in the Pz-F3 cross-PAC.
