Temporal Changes of Cerebral Blood Flow for Stroop Color-Word Test: A Near-Infrared Spectroscopy Study
This paper attempts to estimate a level of concentration focusing on temporal changes of cerebral blood flow (CBF) for Stroop color-word test (SCWT) which is sometimes used in psychiatric research to induce prefrontal cerebral blood flow changes reflecting cognitive functions. The CBF is measured by near-infrared spectroscopy (NIRS) instrument and processed by time synchronous averaging (TSA). Then, the distinction of the concentration from the TSA waveforms is also discussed.
