Figure 2. Frame-by-frame head displacement is related to frame-by-frame changes in rs-fcMRI signal throughout the brain and across subjects.

Figure 2

(A) For each frame of data in the same subject used in Figure 1, the framewise displacement (FD) of a frame of data is plotted against the absolute values of the differentials of rs-fcMRI timecourses of 264 ROIs (locations listed and shown in Table S1 and Figure S3). These data are fitted with a loess curve (black line) sampling the nearest 5000 data points. (B) Identically produced loess curves from all 22 subjects in Cohort 1 are plotted against framewise displacement. There is a clear trend for larger frame-by-frame head displacement to co-occur with larger changes in rs-fcMRI signal. The inset magnifies the plot between framewise displacements of 0 and 1, demonstrating that this relationship exists even for very small movements.
