Abstract
This chapter discusses the main neuroimaging techniques that can be used to study food related brain processes and gut-brain interactions in humans and provides examples of relevant neuroimaging work in humans. Most commonly used neuroimaging techniques are positron emission tomography (PET), magnetic resonance imaging (MRI), electroencephalography (EEG), and magnetoencephalography (MEG). These techniques are explained with their strengths and weaknesses. There is a clear advantage with PET and functional MRI (fMRI), because both methods are suited to measure deeper brain structures with reasonable spatial and temporal resolution. MEG and EEG can be applied in particular to investigate higher cortical functions, such as cognitive control and their modulation by peripheral appetite signals. There is surprisingly little human work on the modulation of neuronal activity and food cue induced brain reactivity by nutrients and appetite hormones. The chapter reviews different types of human studies.
