Ghrelin and Dopamine: The Gut-Brain Appetite-Reward Connection
Ghrelin's appetite effects are partly mediated through dopamine reward pathways, with peripheral ghrelin activating VTA dopamine neurons — connecting the hunger hormone to food reward and potentially addiction.
Quick Facts
What This Study Found
Peripheral ghrelin activates mesolimbic dopamine reward pathways (VTA → nucleus accumbens), linking the hunger hormone to food reward and hedonic eating — a gut-brain-dopamine axis connecting appetite to pleasure and potentially to addictive eating behavior.
