    The changes in cortical blood flow and blood volume of guinea pigs during auditory stimulation are measured by optical imaging systems. In this study, the change in blood flow distribution was measured by the laser speckle method and the change in blood volume was measured by the multi-spectral imaging system. The significant increase in blood flow and volume was observed around one side of the auditory area just after the onset of the stimulation. The decrease in blood volume around the other side of the auditory area was observed whereas the blood flow surrounding the auditory area is decreased during the post-resting period.
