Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in decision-making from pre to post stimulation assessed with the Balloon Analogue Risk Task | 10 minutes before and immediately after the 30 minutes of non invasive brain stimulation |
Secondary
| Measure | Time frame |
|---|---|
| Changes in brain activity assessed between before and during stimulation measured with functional magnetic resonance (fMRI) | 20 minutes before and immediately after the 30 minutes of non invasive brain stimulation |
| Neural metabolites concentrations measured with magnetic resonance spectroscopy (MRS) | 20 minutes before and immediately after the 30 minutes of non invasive brain stimulation |
| Change in Craving from pre to post stimulation assessed with a single standardized scale | 7 minutes before and 3 minutes after the end of the 30 minutes of non invasive brain stimulation |
