Functional connectivity from reward (nucleus accumbens) and cognitive control (dorsolateral prefrontal cortex) networks predicts body mass index in 61 women, with correlations rs = .33–.46.
- Why it matters: BED is linked to obesity and brain changes, but there is no replicable fMRI connectivity signature that separates BED from related eating phenotypes.
- What they did: Resting-state and task-based (food bidding) seed-based FC fingerprints from NAcc and dlPFC were used to predict group status or BMI, and spatial FC patterns were tested for associations.
- The result: FC robustly predicted BMI across conditions (dlPFC: resting p=.002, task p=.012; NAcc: task p=.007) but failed to classify BED versus subBED or noBE better than chance.
