Verb generation tasks have been exclusively used in the past to study neural activity associated with language processing and has also shown to be a reliable predictor of laterality in contrast to simple picture naming or word reading tasks. The goal of this study was to develop a task which could be used to understand differences in brain areas recruited in identifying differential difficulty stimuli based on reaction times which could be used in assessment of aphasia therapy. Differential level of activation was seen in the inferior frontal gyrus (BA45) with a longer hemodynamic response associated with the difficult stimuli.
