    Ivan E de Araujo
    Department of Neurobiology, Duke University Medical Center, Durham, NC 27710, USA
    Neuron 57:930-41. 2008
    ..Our findings suggest that calorie-rich nutrients can directly influence brain reward circuits that control food intake independently of palatability or functional taste transduction...
  2. doi request reprint Metabolic sensing in brain dopamine systems
    Ivan E de Araujo
    The John B Pierce Laboratory and Department of Psychiatry, Yale University School of Medicine, 290 Congress Avenue, New Haven, CT 06519, USA
    Results Probl Cell Differ 52:69-86. 2010
    ..In particular, it suggests a role for brain dopamine reward systems as metabolic sensors, allowing for signals generated by the metabolic utilization of nutrients to regulate neurotransmitter release and food reinforcement...

    Ivan E de Araujo
    The John B Pierce Laboratory, New Haven, CT 06519, USA
    Curr Biol 23:878-83. 2013
    ..We conclude that glucose metabolism is a critical signal regulating NAcc and hypothalamic response to food cues, and that this process operates independently from the ability of calories to condition liking...

    Int J Obes (Lond) 33:S34-43. 2009
    ..Therefore, rather than working as the receptive field of peripheral taste receptor cells, the central gustatory pathways seem to operate as a multisensory system dedicated to evaluating the biological significance of intra-oral stimuli...

    Science 341:800-2. 2013
    ..Our findings suggest that high-fat-induced gastrointestinal dysfunctions play a key role in dopamine deficiency and that restoring gut-generated lipid signaling may increase the reward value of less palatable, yet healthier, foods. ..
