Inter and Intra regions gamma synchronization and co-activation. Co-activation (A1) and synchronization (B1) in the gamma band between DMPFC and LPFC and between each of the DMPFC sub regions; pre-SMA, and SMA proper with the LPFC (A2, B2) was significantly stronger for internally guided action planning. Within regions analysis showed increased co-activation for internally guided action planning within the DMPFC but not within the LPFC (C1). Such an increase was also present for the pre-SMA, but not the SMA proper (C2). Within regions synchronization revealed no difference between the conditions (D1–2). Significant difference between the conditions was tested using sign-test.
