Although the stimuli are presented briefly in the pulsepedestal paradigm, this paradigm favors the PC pathway because both the target and the pedestal are effective stimuli for the MC pathway, which is relatively insensitive to contrast differences under these conditions owing to its nonlinear, saturating contrast gain function. A similar argument can be applied to our brief synchronous condition.
