Spatiotemporal correlations of loci displacements. (A) Normalized matrices of pair correlation of motions $\overline{C_{ij}}$ for the null model (top), mouse (middle), and Drosophila (bottom) at different time lags. Insets represent zooms of the 2 Mbp × 2 Mbp central parts of the matrices. (B,C) Normalized average correlations as a function of the genomic distance (B) and spatial distance (C) for the time lags displayed in A. Arrows indicate increasing time lag.
