This thesis aims to demonstrate the central role of opioid system in developing and maintaining addiction in two behavioural addiction models: sport addiction and anorexia nervosa.It presents an original, multidisciplinary and transversal approach using modern and innovative tools, with a brain imagery using [11C]-diprenorphine PET-scan as main process. We attempt to get receptor density mapping using a SRTM model. Images obtained by this way were then exploited by voxel-based analysis using SPM12. Statistical parametric comparisons include several variables, covariables and regression parameters extracted from complementary exams (psychometric tests, anthropometric measurements, biological samplings especially peripheric circulating opioid...
