Serotonin role on brain circuits involved in food avoidance in anorexia nervosa : Study of Gaze control and multimodal Brain imaging.

This study is trying to understand more about anorexia nervosa, a serious eating disorder where people intensely fear gaining weight and often have a distorted body image. Researchers believe that a brain chemical called serotonin might play a big role in why people with anorexia nervosa avoid certain foods. This study will use very advanced scanning techniques to look at the brain and see how serotonin is working.

They're particularly interested in how serotonin affects the brain circuits (pathways) that control things like avoiding food. By using a combination of special brain scans, like PET and MRI, alongside tracking eye movements when people look at food, scientists hope to get a clearer picture of what's happening in the brain. They will also ask participants about their feelings towards food to understand their choices and preferences.

This research is important because the more we understand about the brain processes involved in anorexia nervosa, the better we can develop new and more effective treatments in the future. It’s part of a bigger effort to help people with this condition. This study is in a later stage (Phase III), which means previous research has already suggested that looking at serotonin could be a promising area.
