Recent functional neuroimaging studies suggested that distinct neural networks are recruited for regulating response and perceptual conflict separately. We employed a conflict adjustment paradigm using a modified Stroop task to verify the multiple conflict-driven cognitive control networks. Neuroimaging results demonstrated that the cdACC and the pre-PMd are involved in detecting and regulating perceptual conflict, respectively, which is analogous to the recruitment of the rdACC and the DLPFC in control processes for response conflict. We also investigated neural networks for detection and regulation of stimulus/response conflict in multiple-conflict situations by developing the OX-arrow conflict task, where "stimulus + response" and "response + response" conditions could be manipulated to measure stimulus-conflict and response-conflict separately. With the experimental results, the independence of underlying neural networks for conflict-driven cognitive control will be discussed.
