Node Detection Using High-Dimensional Fuzzy Parcellation Applied to the Insular Cortex

Figure 2

High-dimensional clusterization and node creation of the insular cortex. (a) High-dimensional insular clusterization. Homogeneous areas are shown in green and borders in blue. The dotted red line outlines the separation between anterior and posterior clusters as detected in our previous studies [8, 33]. (b) Upper panels: anterior- and posterior-cluster functional connectivity. (b) Lower panels: patterns of functional connectivity regressing out the common variance. (c) Reliability of node creation. Nodes calculated from the main group are shown in red, nodes calculated from the replication group in blue. If separated, paired nodes are shown by a dotted red line.
