Brain activation during the three experimental conditions. A. Activation in the whole brain (hot colors indicate an increase in oxygenated hemoglobin [oxy-Hb] changes; cold colors indicate a decrease in oxy-Hb changes). B. Activation in the five functional near-infrared spectroscopy channels that showed stress-related brain activation. The error bars indicate 1 standard error. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
