Fig. 4 — The consistency of brain region-based correlation coefficients of different types. (a) Four kinds of neurovascular coupling biomarkers were calculated by using only parametric maps of HC group. Even the calculating methods of ALFF map, fALFF map, DCP map, and DCN map were totally different, the distribution and fluctuation of their brain region-based correlation coefficients with CBF map were similar. (b) The reconstructed brain maps of these 4 types of brain region-based correlation coefficients.
