DESCRIPTION:The conscious perception of the hedonic sensory properties of 
 caloric foods is commonly believed to guide our dietary choices. Current a
 nd traditional models implicate these consciously perceived hedonic qualit
 ies of food as driving overeating\, whereas subliminal signals arising fro
 m the gut would curb our uncontrolled desire for calories. In this talk I 
 will review recent animal and human studies that support a markedly differ
 ent model for food reward.  These findings reveal in particular the existe
 nce of subcortical body-to-brain neural pathways linking gastrointestinal 
 nutrient sensors to the brain’s reward regions. In this model\, gut-brai
 n reward pathways bypass cranial taste and aroma sensory receptors and the
  cortical networks that give rise to flavor perception. They instead reinf
 orce behaviors independently of the cognitive processes that support overt
  insights in the nature of our dietary decisions. We will also consider se
 veral examples of how modern processed foods impact this circuit to drive 
 overeating.\n\n
