Beyond High-Amplitude Events: Amplitude-Resolved Spatial and Temporal ICA Representations in fMRI
Functional MRI analyses commonly reduce high-dimensional brain activity using predefined spatial summaries, such as region-of-interest (ROI) averages, or temporally selective representations, such as co-activation patterns (CAPs) and high-amplitude events. These approaches provide useful summaries but do not explicitly characterize information distribution across the continuous magnitude of…
