Functional MR imaging taken while the animals received either a juice reward or VTA stimulation revealed that both induced activation of brain regions that previous studies in humans and other primates have associated with reward signaling by means of the neurotransmitter dopamine.
As the study was conducted in a brain scanner at the LIFE&BRAIN Center in Bonn, researchers could also show that products labeled with this emblem led to increased activity in specific brain regions: For example, they observed increased activation in regions important for reward processing as well as frontal regions that process abstract product attributes (e.g. whether or not a product carries a Fair Trade logo, and the meaning of such a label).
