Abstract

Research conducted with adults has demonstrated increased neural response to high calorie food images among sleep-deprived individuals (Benedict et al., 2012). Furthermore, a significant body of research suggests that social stress increases risk for unhealthy food consumption. Research examining the neural underpinnings of the social stress suggests that activation in brain regions implicated in reward and threat processing (e.g., amygdala, striatum) may be activated by social threat while inhibitory control regions (e.g., prefrontal cortex) are less active. This study was designed to examine potential differences in brain responses to peer feedback that reflects succeptibility to social rejection when sleep restricted using a within-subjects experimentally manipulated sleep duration modification paradigm. We also aimed to examine the effect of brain activation patterns on energy consumption during an ad libitum meal.
