FMRI is used to investigate cortical activity based on BOLD response. In this study, carbogen modulation is introduced to enhance BOLD response because of vascular autoregulation. The visual tasks with and without carbogen inhalation were proposed to show the dynamic coupling between carbogen inhalation and BOLD response. The results demonstrated significant BOLD increase by carbogen modulation.
