Figure 2. Hierarchically structured face-processing network.

(A) Dendrogram from the hierarchy clustering analysis based on the strength of functional connectivity among the face-selective ROIs when the participants performed a face recognition task. The face-processing network consists of three relatively independent sub-networks that correspond to the recognition of individual identity (Identification), retrieval of personal knowledge (Semantic) and analysis of facial expression (Expression). (B) Sub-networks are displayed on the mean MNI152 brain surface with nodes and edges. The sub-network for Identification, Semantic, and Expression is colored with blue, red and green, respectively. Note that for display purposes, edges between the sub-networks are not shown.
