Connectome-based Neurofeedback of the Craving Network to Reduce Food Cue Reactivity
Yale University
Summary
This project tests whether individuals with overweight or obesity and high craving can learn to change their brain response to food cues using neurofeedback, to impact their craving and eating behavior.
Description
Aim 1 of this study is to test whether neurofeedback from the craving network is associated with reduced craving network strength. Aim 2 of this study is to test whether neurofeedback from the craving network is associated with reduced food craving and changes in eating behavior. Aim 3 of this study is to test whether neurofeedback from the craving network is associated with changes in resting state functional connectivity.

Interventions
- DeviceExperimental feedback
Participants provided with feedback of target brain activation patterns (e.g., thermometer) and will be instructed to try to change the feedback (e.g., decrease the thermometer).
- DeviceControl feedback
Participants provided with control (sham, yoked to another participant) feedback (e.g., thermometer) and will be instructed to try to change the feedback (e.g., decrease the thermometer).
