Abstract:
Brain insulin action was measured in adolescents with (cases) and without (controls) depression, by calculating the difference in resting-state functional connectivity (ΔrsFC) following an intranasal insulin challenge. A significant Group × Condition interaction effect was identified: controls exhibited greater ΔrsFC with intranasal insulin compared to cases in brain regions regulating cognitive/emotional processing.
