This study examined blood oxygenation changes during a modified Stroop task with colored Chinese words using functional near‐infrared spectroscopy (fNIRS) in patients poststroke aphasia. The included three conditions: neutral, congruent, and incongruent. Participants consisted of 15 healthy adults Compared to adults, aphasic showed significantly longer reaction times reduced accuracy across all conditions, more pronounced interference effect the incongruent condition. fNIRS analysis revealed distinct neurophysiological differences: decreased activation Broca’s area, increased ventromedial frontal pole, atypical recruitment left dorsolateral prefrontal cortex (DLPFC) tasks. These findings highlight differing neural mechanisms underlying cognitive integration enhances our understanding intentional inhibition deficits impact patients. Importantly, these results suggest that control abnormalities regions, such as pole DLPFC, may be potential targets for noninvasive neuromodulation improve observed patterns regions underscore their critical role managing inhibition. Noninvasive brain modulation techniques offer promising strategies modulating mechanisms. underscores need targeted interventions address dysfunctions emphasizes value visual language tasks exploring complex relationship between this population.
