  • Errors are displayed as SEM.

  • ↵F1-a  Pump duration was defined as the time from the peak of the E-phase transient to the peak of the R-phase transient (Raizen and Avery, 1994).

  • ↵F1-b  M3 transients were identified with an algorithm as described in Iwasaki et al.(1997).

  • ↵F1-c  M3 amplitudes are normalized to the amplitude of the R-phase transient.
