The focus of the fMRI analysis was on brain regions implicated in reward and reward valuation, including the orbitofrontal cortex, dorsolateral prefrontal cortex, striatum (caudate, nucleus accumbens, putamen), insula, midbrain, and amygdala, as these regions are activated by desire and rewarding experience, such as consuming high-sugar food.
