Paper Abstract

Investigation of the reliability and reproducibility of the hemodynamic response is important for interpretation and understanding of the results of functional near-infrared spectroscopy (fNIRS). It measures optical signals absorbed by the brain tissue and reflects the neuronal activities indirectly. Here we described an fNIRS study measured in the prefrontal region (Brodman area 9, 10, part of 46)to examine the risk decision-making behavior in nine young adults. The Balloon Analog Risk Task (BART) is widely used to test the level of risk taking ability in the field of psychology. BART was a protocol utilized in this study to evoke a risk-taking environment with a gambling-like balloon game in each subject. Specifically, we recorded the brain oxygenated-hemoglobin (HbO) and deoxygenated-hemoglobin (HHb) changes during the two repeated measurements within a time interval of 3 weeks. The results demonstrate that the changes in HbO2 amplitudes have high reliability at the group level, and that the spatial patterns of the tomographic images have high reproducibility in size and a moderate degree of overlap. Overall, this study confirms that the hemodynamic response to risk decision-making (i.e., BART) seen by fNIRS is highly reliable and reproducible.
