| Research Abstract |
Recently, near-infrared spectroscopy (NIRS) has been used to measure activation of brain cortex. Change of both oxygenated and deoxiganated haemoglobin concentration were measured by optical topography systems (ETG-4000, Hitachi Medical Corporation, Tokyo) under the condition of olfactory or trigeminal stimulations. Although, the oxihemoglobin level with the frontal area of cerebrum accepted a tendency to be elevated by odor stimulation, but oxihemoglobin level from temporal to parietal area was elevated by trigeminal stimulation. However, there were some differences among the subjects.
