Promise and limitations of functional neuroimaging in the study of obesity: is it time for a consortium and a multicenter trial?

The author reflects on the limitation on the application of functional neuroimaging (FN) techniques for the investigation of human obesity. He notes that the limitation on the used of FN relates on the understanding of pathophysiology, which persons have gained weight or turn to obesity. The author adds that its studies are resource intensive and logistically complex, which needs costly imaging facilities and expert staff to investigate.
