ABSTRACT 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.

注意调节对正常参与者和发育面容障碍患者的腹侧和背侧面部区域有不同的影响

摘要 面部选择性皮质区域可分为腹侧流和背侧流。先前的研究结果表明，对面部特定方面的选择性关注对这两种流有不同的影响。为了更好地了解面部网络的组织以及注意力调节的缺陷是否会导致发育性面容失认症 (DP)，我们评估了对八个面部选择性区域的不同面部方面的选择性注意的影响。我们对正常参与者的结果发现，当注意力集中在身份和表达上时，腹侧通路（OFA、FFA）中的 ROI 反应强烈，而在引导注意力时，背侧通路（pSTS-FA、IFG-FA）中的 ROI 反应最大到面部表情。通过对不同面部方面的关注产生的响应曲线在 DP 和法线中具有可比性。我们的结果表明注意力调制对腹侧和背侧蒸汽面区域的影响不同，并且表明注意力调制的缺陷对 DP 没有贡献。
