Task-related fMRI subtraction can erase the very activity it aims to measure.

Evidence

The consequence of a task-related design is that, by using a subtraction approach, the tinnitus-related activity, present in both conditions, will not be present in the subtraction image unless the task affects the perception of tinnitus (Lanting et al. 2009 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2747 (#exemplifies, via linked claim)
