Surface plots for each CAP are paired with radar plots depicting the cosine similarity between each CAP and various HCPex cortical divisions. In these radar plots, “High Amplitude” (shown in red) represents the cosine similarity between the cortical division and the positive activations in the cluster centroid, while “Low Amplitude” (shown in blue) represents the cosine similarity between the cortical division and the negative activations in a CAP cluster centroid. The radial axis of each radar plot shows cosine similarity values ranging from 0 to 0.5. Note that during computation, the inverse values of the negative activations were calculated to restrict the cosine similarity for both positive and negative activations in a CAP from 0 to 1. At the bottom right, a depiction of each HCPex cortical division (excluding the subcortical areas) is shown. The labels for each CAP show the network correspondence of cosine similarities ≥0.20.
