While results are somewhat contradictory, studies have in fact found increased right hemispheric activation in non-fluent aphasic patients after MIT. This change in activation has been interpreted as evidence of decreased dependence on the left hemisphere. There is debate, however, as to whether changes in right hemispheric activation are part of the therapeutic process during/after MIT, or are simply a side effect of non-fluent aphasia. In hopes of making MIT more effective, researchers are continually studying the mechanisms of MIT and non-fluent aphasia.
