A step forward in the understanding of prefrontal cortical functions

引用

Neuroscience Bulletin 2015年第2期31卷 161-163页

作者： Bao-Ming Li shintaro funahashi Institute of Life Science Nanchang University Kokoro Research Center Kyoto University

The prefrontal cortex （PFC） is an integrative area that guides behaviors and thoughts. During the past century, a great many studies have been performed on PFC functions, using a variety of technical approaches such as anatomy, lesion, neuropsychology, electrophysiology, and functional imaging. It is well known that the PFC plays an essential role in inhibitory control of behavior, regulation of attention, working memory, decision-making, and behavioral oraanization.

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.
