Fig. 4.

Effects of DIIV and HRF on the inter-individual variations of CDE curves. a–c CDE of the multivariate Gaussian data with DIIV = 0, 5, and 10 respectively. The SNR = 5 dB and the number of communities $K$ = 6 for all experiments. d–f The extrema of the individual-level CDE curves with different levels of DIIV. The red dots are the local maxima and the blue dots are the local minima of 100 virtual subjects. g–i CDE curves of the multivariate Gaussian data applied with haemodynamic response function (HRF). j–l The extrema of the individual-level CDE curves with HRF. m The time deviation of local maxima of individual-level CDE curves compared to the local maximum of the group-averaged CDE curve with different levels of DIIV and HRF. n The time deviation of local minima of individual-level CDE curves compared to the local minimum of the group-averaged CDE curve with different levels of DIIV and HRF.
