本研究采用一种神经适应范式，即快速连续呈现适应刺激和测试刺激，以探讨面孔敏感N170成分与图形面孔加工之间的联系。在实验1中，示意性适配器刺激前直立的脸，倒置的脸，或孤立的眼睛自然的图像。相对于基线条件与示意性的房子适配器，直立和倒置的示意性的脸适应N170随后的自然的脸，表明该组件与神经过程中涉及的一阶关系的脸配置的分析。在实验2中，双色调的门尼脸适应N170自然的面孔相对于基线条件与门尼的房子，这表明N170和整体的脸处理之间的联系。结果表明，N170分量不仅反映了单个人脸部分的检测和分析，而且还反映了人脸的一阶几何和全局完形特征的处理。他们还表明，神经适应程序可用于识别负责类别特定ERP组件（如N170）的神经机制。(C)2010 Elsevier B.V.保留所有权利。
A neural adaptation paradigm where adaptor and test stimuli were presented in rapid succession was employed to investigate links between the face-sensitive N170 component and configural face processing. In Experiment 1, schematic adaptor stimuli preceded naturalistic images of upright faces, inverted faces, or isolated eyes. Relative to a baseline condition with schematic house adaptors, upright and inverted schematic faces adapted the N170 to subsequent naturalistic faces, demonstrating that this component is associated with neural processes involved in the analysis of first-order relational face configuration. In Experiment 2, two-tone Mooney faces adapted the N170 to naturalistic faces relative to a baseline condition with Mooney houses, suggesting links between the N170 and holistic face processing. Results demonstrate that the N170 component does not exclusively reflect the detection and analysis of individual face parts, but also the processing of first-order configural and global gestalt features of faces. They also show that neural adaptation procedures can be used to identify the neural mechanisms that are responsible for category-specific ERP components such as the N170. (C) 2010 Elsevier B.V.
