Having to decide in a simulation between saving one’s sister, friend, and others from crisis regions elicited significant brain activity in the VMPFC, ACC, precuneus, DLPFC, IFG, insula, TPJ and MTG. These activations of subjects (N = 30) were obtained by contrasting the decision phases (from the point of revealing the individuals involved until the decision signaled by the subject’s button press) against non-decision phases (subjects watching the background story depicting the two crisis regions and how the subjects only have resources to save individuals from one of the crisis regions) (FDR q < 0.05, t = 2.0384, for consistent illustration purposes, the figures shows t-values from 3 to 9) Left-lateralized motor and supplementary motor are probably explained by the button press that the subjects performed to announce their decision. Abbreviations: ACC = anterior cingulate cortex, DLPFC = dorsolateral prefrontal cortex, IFG = inferior frontal gyrus, IOG = inferior occipital gyrus, ITG = inferior temporal gyrus, MC = motor cortex, MFC = medial frontal cortex, MOG = middle occipital gyrus, MTG = middle temporal gyrus, PCC = posterior cingulate cortex. SMA = supplementary motor area, SPL = superior parietal lobe, TPJ = temporo-parietal junction,VMPFC = ventromedial prefrontal cortex, a = anterior, d = dorsal, p = posterior, v = ventral.
