The group average pattern of brain activation for each of three increasingly difficult items (from left to right) on a problem-solving task that requires both executive functioning and spatial processing As shown, the amount of activation in this slice of the brain increases with difficulty in the prefrontal cortex (toward the front of the brain, often involved in executive functioning) and in the superior parietal cortex (toward the back of the brain, often involved in spatial processing).
