“…However, in this case, the frequency contributing to the PAC signal was in the beta range, whereas in our case, it was in the theta/delta range. Even though the beta band is considered very important for the motor function in PD, connections to the motor function could also be established for the theta/delta band ( Brauns et al, 2014 ; Hamel-Thibault et al, 2018 ; van der Cruijsen et al, 2021 ). Since cortical network formation in PD also occurs in the theta/delta band ( Sharma et al, 2021 ), this work further highlights that when looking at PAC in PD, broadband oscillatory activity, i.e., not only beta, should be considered.…”
