A6 - Combining real-time brain imaging with neurofeedback to modulate the desire for food

This project has been funded by the DFG from 2013 to 2016.

Growing evidence suggests that obesity is linked to an imbalance between the brain’s homeostatic, hedonic, and cognitive control systems. Given virtually unlimited access to high-caloric food, it is important to keep control over hedonic systems to avoid eating beyond energy demand. In a recent study, we investigated how the brain allows lean individuals to consciously regulate/control the hedonic system and hence the desire for tasty but unhealthy food (Hollmann et al., 2011). We identified the brain’s valuation system in combination with prefrontal cognitive control areas to contribute to active reappraisal of unhealthy food. An insufficient cognitive control capacity of these brain systems represents one crucial mechanism in the development of obesity. Here, we aim to combine real-time functional magnetic resonance imaging (rt-fMRI) with neurofeedback to train obese subjects on strengthening cognitive control over the hedonic brain system and hence overeating behavior. We acquire hemodynamic brain responses from obese subjects in real-time to continuously monitor current brain states. The difference between this state and a state of optimized cognitive control will be translated into a single signal and visually backprojected to the subject on-line (i.e. neurofeedback). With the following presentations subjects will be trained to continuously adapt their current brain state to a state of optimized cognitive control. We aim at comparing two different training approaches: training (i) on one’s own brain pattern of optimized control, or (ii) on brain patterns of lean subjects. We hypothesize that with ongoing neurofeedback training, subjects progressively learn to use the most advantageous strategy in order to gain control over desire for unhealthy food. Strengthening cognitive control over eating through neurofeedback represents a promising approach for the development of new treatment strategies in obesity.
