What the trial is, and whether it could suit you
Emotional overeating is characterized by an excessive food intake in the context of intense emotional situations, such as acute stress one. Emotional overeating, as a behavioral trait, can increase the risk of to develop eating disorders or eating-related diseases, such as metabolic syndrome, obesity, type-2 diabetes. Recently, imaging modalities, such as magnetic resonance imaging (MRI) and electro-encephalography (EEG), have been adapted in order to perform neurofeedback consisting on presenting the brain activity instantaneously to the participant, that give him the possibility to modify this activity by his own mean. Neurofeedback has already shown some efficacy, either with explicit or implicit instruction.
Compared with functional MRI (fMRI), functional near infra-red spectroscopy (fNIRS) is easy to handle, less expensive, and does not require a lying position. fNIRS is consequent
