Fig. 2: Classification analyses based on neural activations beyond the ‘threat circuit’.
From: Distributed neural representations of conditioned threat in the human brain
A Cross-validation performance on the discovery dataset (n = 425). Voxel activations from the whole brain (with voxels that belong in or are close to the ‘threat circuit’ excluded) were used for the classification. B, C Generalizations on the validation dataset 1 (n = 98) and the validation dataset 2 (n = 127). Error bars in panels A–C are SEM for accuracies. D Predictive patterns of voxels across the brain. A voxel with red/blue color indicates that this voxel is more activated to CS + /CS-. Permutation tests were conducted to assess the voxel contributions to the classification. Only voxels that significantly contributed to the classification (p < 0.05, FDR-corrected, two-sided) are shown.
