Feedbacks' Influence on Decision Making Processes
France76 participantsStarted 2017-03-30
Plain-language summary
The purpose of this research is to identify and probe the neural networks involved in feedback processing. It aims at translating this knowledge to clinical populations in which this network is disrupted or compromised.
It includes two studies: 1) with fMRI in healthy subjects to identify the neural bases of feedback processing on decision making using different types of feedback (neutral, social and monetary) presented either infra- or supra-laminary and 2) probing the role of one structure, the anterior cingulate cortex, using Galvanic Vestibular Stimulation (GVS) in healthy subjects. The interventional part consists in the administration of Galvanic Vestibular Stimulation (GVS), which by means of small intensity currents activates the vestibular organs and subsequently vestibular-related brain areas. GVS will be delivered to healthy participants engaged in behavioural tasks requiring the processing of feedbacks of different nature (e.g. social or monetary feedbacks)

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
