Brain areas involved in PI resolution: IFG (inferior frontal gyrus, or mid-ventrolateral prefrontal cortex, vlPFC), pre-SMA (pre-supplementary motor area), dlPFC (dorsolateral prefrontal cortex), PPC (posterior parietal cortex), areas in the MTL (medial-temporal lobe). MTL is in lighter color to indicate its medial position (not visible in this lateral view).
