人脑中三个最强大的功能标志是对梭状面部区域（FFA）中的面部、海马旁区域（PPA）中的场景以及纹状身体区域（EBA）中的身体的选择性反应。这些地区的选择性反应是在发展初期就出现了还是需要很多年才能发展？先前的证据使这个问题悬而未决。我们设计了一种新的 32 通道婴儿磁共振成像 (MRI) 线圈，并在婴儿（2-9 个月大）观看来自四种条件（面部、身体、物体和场景）的刺激时收集了高质量的功能性 MRI (fMRI) 数据。我们发现婴儿在成人 FFA、PPA 和 EBA 的位置上分别具有面部、场景和身体选择性反应，这有力地限制了皮质发育的解释。
Three of the most robust functional landmarks in the human brain are the selective responses to faces in the fusiform face area (FFA), scenes in the parahippocampal place area (PPA), and bodies in the extrastriate body area (EBA). Are the selective responses of these regions present early in development or do they require many years to develop? Prior evidence leaves this question unresolved. We designed a new 32-channel infant magnetic resonance imaging (MRI) coil and collected high-quality functional MRI (fMRI) data from infants (2-9 months of age) while they viewed stimuli from four conditions-faces, bodies, objects, and scenes. We find that infants have face-, scene-, and body-selective responses in the location of the adult FFA, PPA, and EBA, respectively, powerfully constraining accounts of cortical development.
