REG P1 and P2 amplitudes (means of 5-10 pulse peak values) during control and HDT in four subjects, calculated from pulse waves presented in Fig_ 6_ The amplitude difference was calculated as a percentage of the control/baseline (BL%)_ REGx R2: correlation coefficient of bifrontal and bitemporal REGx during the full time of the recording_ The sample traces are presented in Fig_6_ Arm bioimpedance recordings were missing in the case of the 4_5_1 subject, consequently, there was no REGx calculation_
