IntroductionShort sleep duration promotes metabolic dysregulation and obesity. We have previously shown that acute sleep restriction increases neuronal activity in response to food stimuli in areas of interoception and reward, such as the insula and orbitofrontal cortex. However, whether chronic mild sleep restriction impacts food reward valuation in the brain remains unknown. In an ongoing study, we assess the effects of mild 6-week sleep restriction on intrinsic functional connectivity (iFC) across reward and interoception-related brain circuitry.
