On the other hand, in animal studies, there is no optical imaging system for evaluating changes in CBF and CBV, and oxygen metabolism, from the same brain area under awake condition. In the present study, we developed a simultaneous measurement system of laser speckle imaging (LSI) and intrinsic optical signal imaging (IOSI), which was verified by laser–Doppler flowmetry (LDF). Moreover, to measure oxygen metabolism, flavoprotein autofluorescence imaging (FAI) was performed from the same brain area as LSI and IOSI measurements. The change in CBF according to LSI was correlated with that by LDF. Similarly, the change in CBV obtained by IOSI was also correlated with RBC concentration change measured by LDF. The change in oxygen metabolism by FAI was correlated with that in CBF obtained by LSI, although the change in CBF was greater than that in oxygen metabolism. We revealed that the relationship between oxygen metabolism and CBF as measured by our system was in good agreement with the relationship between CMRO2 and CBF in human PET studies. Our measurement system of CBF, CBV and oxygen metabolism is not only useful for studying neurovascular coupling, but also easily corroborates human PET studies.
