Figure 4. Effects of oxytocin and types on amygdala: The bar diagram illustrates parameter estimates derived from the right amygdala (21, −3, 18) revealed in the three-way interaction (pain, drug, prosociality) in self. Contrast estimates on the contrast (pain vs. no pain) are shown for the self (green) and the other (red) in the placebo (filled), and oxytocin (shaded) conditions, separately for prosocial and selfish participants. Threshold is set at p < .001, uncorrected.
