摘      要：The activity of occipitotemporal regions involved in linguistic reading processes,such as the ventral occipitotemporal cortex(vOT),is believed to exhibit strong interactions during higher-order language processing,specifically in the connectivity between the occipital gyrus and the temporal *** this study,we utilized functional magnetic resonance imaging(fMRI)with psychophysiological interaction(PPI)and dynamic causal modeling(DCM)to investigate the functional and effective connectivity in the occipitotemporal network during speed *** conducted the experiment with native Japanese speakers who underwent and without speed-reading training and subsequently performed established reading tasks at different speeds(slow,medium,and fast)while undergoing 3-Tesla Siemens *** activation analyses revealed significant changes in occipital and temporal regions as reading speed increased,indicating functional connectivity within the occipitotemporal *** results further demonstrated more intricate effective connections and high involvement within the occipitotemporal pathway:(1)reading signals originated from the inferior occipital gyrus(iO),distributed to the vOT and the posterior superior temporal sulcus(pSTS),and then gathered in the anterior superior temporal sulcus(aSTS);(2)reading speed loads had modulation effects on the pathways from the aSTS to vOT and from the iO to *** findings highlight the complex connectivity and dynamic interactions within the occipitotemporal network during speed-reading processes.
