ΔHbR components and fMRI “snapshots”: on the left of each window is shown a linear combination of the fMRI maps that are well-correlated with physiology and body movement noise (composite ICs 2, 4, and 5), weighted by the ΔHbR part of the components at a specific point in time. On the right of each window is shown the estimated ΔHbR components that are correlated physiology and body movement noise. The time courses for IC2 (in blue), IC4 (in green) and IC5 (in red) are also plotted on the right of each window. Such a display provides a dynamic way to visualize how the noise affects the brain activity at different time points: −14518 ms (A), −9391 ms (B), −3734 ms (C), 7052 ms (D) and 13946 ms (E).
