Figure 2

Brain activation for gain, draw and loss during anticipation and experience. The red, green and blue represented the gain, draw and loss respectively. The upper figure showed the brain activations in these three conditions during anticipation (Random Effect: all conditions, P _uncorrected = 0.0001, K = 30). Most regions of three conditions overlap during the anticipation stage. The bottom lower figure indicated that different monetary consequences activated different brain regions for different outcomes (Random Effect: Gain: P _uncorrected = 0.0001, K = 30; Draw: P _uncorrected = 0.001, K = 10; Loss: P _uncorrected = 0.001, K = 10. The threshold levels were adjusted for visualization and discussion purpose due to the differences of trial numbers in different conditions, inherent in the IGT.
