Appetite and Reward Signals in the Brain: Sugar Intake Effects on Brain Activity as Measured by Functional Magnetic Resonance Imaging

摘要: Functional magnetic resonance imaging (fMRI) is a relatively new tool used to monitor the brain’s responses changes in diet. In this chapter, we summarize rapidly growing literature on how brain responds sugar, as measured by blood oxygenated level dependent (i.e. BOLD) fMRI analyses. The chapter starts providing an overview of what known about control food intake, from hypothalamic mechanisms hindbrain-sensory integration reward mechanisms. We then available work measuring response different sugars, including analyses focusing not only glucose, sucrose, and fructose but also several extra regions, amygdala frontal cortex. believe that these will ultimately contribute better understanding sweetened beverages are readily consumed excess need bypassing for controlling intake.
