大脑通过腹侧视觉通路上的一系列区域处理物体，但支持特定复杂形式分析的电路仍然未知。面部是一种复杂的形态类别，有选择地激活猕猴腹侧通路中的六个皮层。为了识别这些面部斑块的连通性，我们使用电微刺激结合同步功能磁共振成像。对四个目标面部斑块中的每一个的刺激都会产生强烈的激活，特别是在其他面部斑块的子集中。面部贴片外部的刺激产生了一种激活模式，使面部贴片幸免于难。这些结果表明，面部斑块形成了一个强大且特定互连的分层网络。
The brain processes objects through a series of regions along the ventral visual pathway, but the circuitry subserving the analysis of specific complex forms remains unknown. One complex form category, faces, selectively activates six patches of cortex in the macaque ventral pathway. To identify the connectivity of these face patches, we used electrical microstimulation combined with simultaneous functional magnetic resonance imaging. Stimulation of each of four targeted face patches produced strong activation, specifically within a subset of the other face patches. Stimulation outside the face patches produced an activation pattern that spared the face patches. These results suggest that the face patches form a strongly and specifically interconnected hierarchical network.
