Fig. 5

a sO2 image of the whole cortex at baseline. b, c Close-up sO2 images of the SD wave origin at 330 s and 411 s after releasing the right carotid artery, as indicated by the white dotted rectangle in (a). Two representative vessels ① and ② were selected for further analysis. d Propagation time map of a representative SD wave. Arrows represent the direction of SD wave. e The change in PA signal intensity during the SD wave propagation at 6 s, 21 s, 36 s and 75 s, respectively. f The change in sO2 during the SD wave propagation. g The diameter change of vessel ① over a SD wave. h The sO2 change of vessel ① over a SD wave. i The diameter change of vessel ②. j The sO2 change of vessel ②. Scale bars, 1 mm for (a, d, e, f), 100 μm for (b, c)
