After Dinner, half of the participants was allowed to go home to sleep. The other half of the night had to stay awake.
The next Morning, the Ghrelin content of the blood were in two groups-the information about the feeling of satiety of people out there – and the brain activity of the participants in the MRI-device was investigated.
