899 Sleep Deprivation Effects on Monetary Rewards—Libedinsky et al INTRODUCTION An increasing number of persons do not get adequate sleep.1 Experimentally induced sleep deprivation has been shown to affect decision-making, including risky behavior, in simulated real-world scenarios2,3 and laboratory settings.4-8 Increased risk taking in these studies could have arisen from altered valuation of rewards during sleep deprivation. Supporting this notion, functional neuroimaging studies on risky decision-making during sleep deprivation have shown increased activation of brain areas involved in reward valuation.8-10 However, a direct examination for change in valuation of social and monetary rewards as a result of sleep deprivation found neither a systematic state-related change in behavior nor a consistent increase in money valuation signals in the brain.11 An alternative mechanism through which sleep deprivation may result in increased risk taking is that it may increase one’s tendency to make impulsive decisions. Although different facets of impulsive behavior have been studied,12-15 cognitive impulSLEEP DEPRIVATION EFFECTS ON MONETARY REWARDS

A Genetic Polymorphism of the Human Dopamine Transporter Determines the Impact of Sleep Deprivation on Brain Responses to Rewards and Punishments
Despite an emerging link between alterations in motivated behavior and a lack of sleep, the impact of sleep deprivation on human brain mechanisms of reward and punishment remain largely unknown, as does the role of trait dopamine activity in modulating such effects in the mesolimbic system. Combining fMRI with an established incentive paradigm and individual genotyping, here, we test the hypoth...
متن کاملSleep Deprivation Alters Valuation Signals in the Ventromedial Prefrontal Cortex
Even a single night of total sleep deprivation (SD) can have dramatic effects on economic decision making. Here we tested the novel hypothesis that SD influences economic decisions by altering the valuation process. Using functional magnetic resonance imaging we identified value signals related to the anticipation and the experience of monetary and social rewards (attractive female faces). We t...

Risk in the Iowa Gambling Task (IGT) is often understood in terms of intertemporal choices, i.e., preference for immediate outcomes in favor of delayed outcomes is considered risky decision making. According to behavioral economics, healthy decision makers are expected to refrain from choosing the short-sighted immediate gain because, over time (10 trials of the IGT), the immediate gains result...
