Supplementary tables reporting results from neuropsychological assessments, graph theoretic analyses, seed-to-voxel analyses, ROI-to-ROI analyses, and multiple regression based analyses.

(**a**) Neuropsychological domain performance in the amnesic group. (**b**) Results from graph theoretic analyses of the default network (DN). Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient, and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected analysis threshold (p-FDR <0.05, two-sided) and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**c**) Results from graph theoretic analyses of the somatomotor network. Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient, and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected analysis threshold (p-FDR <0.05, two-sided), and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**d**) Results from graph theoretic analyses of the visual network. Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient, and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected (p-FDR <0.05, two-sided), and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**e**) Results from graph theoretic analyses of the salience network. Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient, and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected (p-FDR <0.05, two-sided), and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**f**) Results from graph theoretic analyses of the ventral attention network. Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected analysis threshold (p-FDR <0.05, two-sided), and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**g**) Results from graph theoretic analyses of the dorsal attention network. Between-group differences in global efficiency, local efficiency, betweenness centrality, average path length, clustering coefficient, and degree were examined. Network edges (adjacency matrix threshold) were thresholded at a *z*-score > 0.84 (one-sided, positive) and assessed at a corrected anaylsis threshold (p-FDR <0.05, two-sided), and, for completeness, at an uncorrected analysis threshold (p-uncorrected <0.05, two-sided). (**h**) Results from graph theoretic stability analyses of default network topology. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the default network was assessed using the *z*-score based adjacency matrix threshold. Nodes that were not significant at the FDR-corrected analysis threshold applied to infer significance are reported at an uncorrected analysis threshold (p*-*uncorrected < 0.05, two-sided). (**i**) Results from graph theoretic stability analyses of somatomotor network topology. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the somatomotor network was assessed using the *z*-score based adjacency matrix threshold. Nodes that were not significant at the p*-*FDR-corrected analysis threshold applied to infer significance are reported at an uncorrected analysis threshold (p*-*uncorrected <0.05, two-sided). (**j**) Results from graph theoretic stability analyses of visual network topology. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the visual network was assessed using the *z*-score based adjacency matrix threshold. Nodes that were not significant at the p*-*FDR-corrected analysis threshold applied to infer significance are reported at an uncorrected analysis threshold (p*-*uncorrected <0.05, two-sided). (**k**) Results from graph theoretic stability analyses of the salience network. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the salience network was assessed using the *z*-score based adjacency matrix threshold.

(**l**) Results from graph theoretic stability analyses of the ventral attention network. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the ventral attention network was assessed using the *z*-score based adjacency matrix threshold. Nodes that were not significant at the p*-*FDR-corrected analysis threshold applied to infer significance are reported at an uncorrected analysis threshold (p*-*uncorrected <0.05, two-sided). (**m**) Results from graph theoretic stability analyses of the dorsal attention network. The amnesic group and the control group were assessed using an adjacency matrix threshold based on cost. The analysis threshold (i.e., p-FDR <0.05, two-sided) was same as when the dorsal attention network was assessed using the *z*-score based adjacency matrix threshold. Nodes that were not significant at the p*-*FDR-corrected analysis threshold applied to infer significance are reported at an uncorrected analysis threshold (p*-*uncorrected <0.05, two-sided). (**n**) MNI co-ordinates for the nodes used in control network analyses. MNI co-ordinates for the nodes that correspond to the somatomotor network, visual network, salience network, dorsal attention network, and ventral attention network were based on the parcellation scheme proposed by Power et al. (2011). Probabilistic anatomical locations of the MNI co-ordinates are defined using the Harvard-Oxford Cortical and Subcortical Probabilistic Atlases. (**o**) Results from between-group seed-to-voxel functional connectivity based analyses. No brain regions exhibited significant differences (height threshold, p-uncorrected <0.001 and an extent threshold of p-FDR <0.05 at the cluster level) in functional connectivity between the amnesic group and the control group, when tested with left and right hippocampal seed regions-of-interest, an occipital pole seed within the visual network, and a seed in primary motor cortex within the somatomotor network. Seed regions were spheres with 8 mm radii. For the left hippocampal seed region, a between-group difference in functional connectivity was found only at a lenient, p-uncorrected <0.05 cluster-size threshold. There were no significant clusters for the right hippocampal seed region, even when between-group differences were assessed at a cluster-size threshold set at p-uncorrected <0.05 (see Figure 7—figure supplement 1). (**p**) Results for left and right hippocampus seed-to-voxel functional connectivity based analyses. MNI co-ordinates of brain regions that exhibited significant functional connectivity with left and right hippocampal seed regions-of-interest shown separately for the amnesic group and the control group (height threshold, p-uncorrected <0.001 and an extent threshold of p-FDR <0.05, at the cluster level). Seed regions were spheres with 8 mm radii (see Figure 7—figure supplement 2). (**q**) Results from robust multiple linear regression analysis on nodes in the default network with significantly increased average path length (independent variables) relative to the control group and total internal (episodic) detail remembered on the AI. Average path length values entered into the robust multiple regression analysis were based on the difference between each participant and the mean of the control group for each affected ROI/node. (**r**) Results from multiple linear regression analysis examining link between nodes in the DN that exhibited significantly different local efficiency and internal (episodic) detail remembered on the AI. Local efficiency values entered into the robust multiple regression analysis were based on the difference between each participant and the mean of the control group for each affected ROI/node.
