Research Abstract

Several studies have claimed that cerebral blood flow signals measured by near-infrared spectroscopy (NIRS) on the forehead showed different patterns in various psychiatric disorders during a verbal fluency task (VFT). In this study, on the other hand, we reported that NIRS signals could reflect task-related changes in skin blood flow. This may indicate a possibility that the NIRS signals used in clinical diagnosis might be influenced by task-related skin hemodynamics. Furthermore, to reveal the physiological mechanism, we clarified the differences in skin hemodynamic responses to VFT between the forehead and the fingertip. We found that the magnitude of the pulsatile component in skin hemodynamic signals increased on the forehead but decreased on the fingertip during the task, whereas the rate increased in both areas. The skin vasomotor system in the forehead could have a different complex sympathetic vascular response mechanism to psychological tasks compared to other areas.
