Time evolving frequency distribution of Her1 protein levels for  k o f f H e r 1 / 7 = 1 / 2  min -1 . The distribution oscillates between low Her1 protein levels with low variability and high Her1 protein levels with high variability. As neighbouring cells desynchronise, the oscillatory behaviour of the frequency distribution is destroyed. See Figs 2C and S3.
