Face-selective cortical areas that can be divided into a ventral stream and a dorsal stream. Previous findings indicate selective attention to particular aspects of faces have different effects on the two streams. To better understand the organization of the face network and whether deficits in attentional modulation contribute to developmental prosopagnosia (DP), we assessed the effect of selective attention to different face aspects across eight face-selective areas. Our results from normal participants found that ROIs in the ventral pathway (OFA, FFA) responded strongly when attention was directed to identity and expression, and ROIs in the dorsal pathway (pSTS-FA, IFG-FA) responded the most when attention was directed to facial expression. Response profiles generated by attention to different face aspects were comparable in DPs and normals. Our results demonstrate attentional modulation affects the ventral and dorsal steam face areas differently and indicate deficits in attentional modulation do not contribute to DP.

脸部选择性皮质区域可分为腹侧流和背侧流。先前的发现表明对面部特定方面的选择性关注对两种流有不同的影响。为了更好地了解人脸网络的组织以及注意调节方面的缺陷是否会导致发展性更年期（DP），我们评估了选择性注意对八个脸部选择区域中不同脸部方面的影响。我们来自正常参与者的结果发现，当注意力集中于身份和表达时，腹侧途径的ROI（OFA，FFA）反应强烈，而当注意力转移时，背侧途径的ROI（pSTS-FA，IFG-FA）反应最大。面部表情。通过注意不同的面部表情而产生的反应曲线在DP和正常人中相当。
