流行的理论表明,负责面部感知的皮层区域以串行、前馈的方式运作。在这里,我们利用侵入性人体电生理学,通​​过测量皮质激活、功能连接和皮质-皮质诱发电位来评估面部处理的系列模型。我们发现,下枕叶(f-IOG)和梭状回(f-FG)面部选择性区域之间的功能连接的任务依赖性变化是双向的,而不是前馈的,并且在从早期视觉皮层(EVC)到这两个区域的前馈输入后出现。皮质-皮质诱发电位同样揭示了 EVC 与 f-IOG 和 f-FG 之间的独立信号传播。这些发现与串行模型不兼容,但支持支撑人类面部感知的并行分布式网络。
Prevailing theories suggests that cortical regions responsible for face perception operate in a serial, feed-forward fashion. Here, we utilize invasive human electrophysiology to evaluate serial models of face-processing via measurements of cortical activation, functional connectivity, and cortico-cortical evoked potentials. We find that task-dependent changes in functional connectivity between face-selective regions in the inferior occipital (f-IOG) and fusiform gyrus (f-FG) are bidirectional, not feed-forward, and emerge following feed-forward input from early visual cortex (EVC) to both of these regions. Cortico-cortical evoked potentials similarly reveal independent signal propagations between EVC and both f-IOG and f-FG. These findings are incompatible with serial models, and support a parallel, distributed network underpinning face perception in humans.
