Neural Dynamics during Resting State: A Functional Magnetic Resonance Imaging Exploration with Reduction and Visualization

Figure 2

BOLD trajectories after projection with jPCA (one color represents one person of the young group; all trajectories were obtained with cubic spline interpolation).

(a) Slow 2 (0.198–0.25 Hz)

(b) Slow 3 (0.073–0.198 Hz)

(c) Slow 4 (0.027–0.073 Hz)

(d) Slow 5 (0.01–0.027 Hz)
