Age Sensitive Hippocampal Functional Connectivity: New Insights from 3D CNNs and Saliency Mapping
A 3D CNN trained on voxel-wise hippocampal functional connectivity predicted chronological age with a 7.30 year MAE on adults aged 36-90, and LayerCAM saliency maps showed age-sensitive connections with precuneus, cuneus, PCC, PHC, left SPL, and right STS.
