Hemodynamic signal change ($\mathrm{\Delta }R/R$) within animals at 2 and 6 weeks postsoft cranial window installation. (a) Optical recording of intrinsic signal (ORIS) set up with whole whisker stimulation (4 s) by air puff. A 570-nm bandpass filter was used. (b) Spatial activation map of ORIS imaging for whole-whisker stimulation in an animal at 2 or 6 weeks postsoft cranial window installation. (c) The graph of $\mathrm{\Delta }R/R$ change of within animals at 2 and 6 weeks postsoft cranial window installation ($n=5$). (d) The peak value of $\mathrm{\Delta }R/R$ change changes within animals at the 2 and 6 weeks postsoft cranial window installation ($n=5$; $p\text{value}=0.0431$).
