行为学和神经心理学研究表明，直立和倒置的面部刺激是由计算和解剖学上不同的系统处理的。具体来说，倒置的面孔似乎是由一般的物体感知系统处理的，避免了特定于面孔的过程。我们通过检查功能定义的梭形面部区域和双侧对象响应皮层区域在感知直立和倒置刺激（面部和汽车）时的fMRI信号响应来测试该模型。虽然倒置的面部刺激对梭状面部区域的反应幅度没有影响，但与物体区域内的直立面部相比，倒置的面部会诱发更大的神经反应。这一发现支持的断言，对象领域涉及到更大程度上的知觉倒置与直立的脸。(C)1999年利平科特威廉姆斯&威尔金斯。
BEHAVIORAL and neuropsychological studies suggest that upright and inverted face stimuli are processed by computationally and anatomically distinct systems. Specifically, inverted faces seem to be addressed by general object perception systems, avoiding face-specific processes. We tested this model by examining the fMRI signal response of a functionally defined fusiform face area and bilateral object-responsive cortical areas during the perception of upright and inverted stimuli (faces and cars). While inversion of face stimuli had no effect upon the magnitude of responses in the fusiform face area, inverted faces evoked greater neural responses compared to upright faces within object regions. This finding supports the assertion that object areas are involved to a greater degree in the perception of inverted vs upright faces. (C) 1999 Lippincott Williams & Wilkins.
