The change in the cortical blood flow of guinea pigs during auditory stimulation is measured by laser speckle flowgraphy (LSFG). Accuracy LSFG depends on number frames for calculation. blood-flow maps rotating disks and tissues are calculated from various numbers pattern, influence statistical error averaging effect results evaluated to optimise system. map obtained successive 24-30 can appropriately identify caused stimulation.
