Chronic itch occurs as a life-distressing symptom of many systemic and skin diseases and is also a frequent symptom in the general population. The physiopathotology of this sensation is still unclear. The purpose of the study was assessment of the cerebral response to itch induced by histamine iontophoresis and show any central modulation of the cortical network involved in itch sensation by a cognitive task, the Stroop task, with PET H215O. Firstly, we have validated the stimulation parameters of our histamine iontophoresis model for itch induction consistent with PET- H215O requirements. Consequently, the model was used in a positron emission topography study and the resulting areas of brain activation were in agreement with previously published studies of this kind. Under Stroop condition the intensity of itching stimulus decreases and the pattern of activation was changed. Periaqueductal grey matter (PAG) seems to be involved in itch modulation. We completed our study by an effective connectivity study that allows us to make an oriented network
