Change in localized brain perfusion patterns during whisker stimulation in lightly sedated mice. (A) In addition to the contralateral right SBF1, the DMN hub RSG (boxed) shows specific CBV decrease during stimulation. Mean values for relative CBV during baseline (OFF stimulation, black) and right whiskers stimulation (white) in percentage of baseline, for each ROI. *P < 0.05; **P < 0.01; ***P < 0.001, Nonparametric Wilcoxon test. Data are presented as mean ± SE (n = 6 mice). (B) Mean rCBV of each ROI is overlaid on a gray-scale vascular image (n = 6 mice).
