- Abstract
To investigate brain activation in the prefrontal cortex (PFC) during the Wisconsin Card Sorting Test (Keio Version) (KWCST), we examined changes in total hemoglobin volume (THV) in 8 patients with traumatic brain injury (TBI) and 20 healthy control subjects using two-channel near-infrared spectroscopy. As a result, average THV in the right PFC during KWCST in TBI patients (-0.131 +/- 0.127) was significantly lower than in control subjects (0.016 +/- 0.135) (2 x 3 ANOVA; p < 0.05). These results demonstrated that the TBI patients had lower circulation of hemoglobin in the right PFC during the KWCST than the control subjects.
