Abstract

Significance In evolved species, resisting the temptation of immediate rewards is a critical ability for the achievement of long-term goals. This self-control ability was found to rely on the lateral prefrontal cortex (LPFC), which also is involved in executive control processes such as working memory or task switching. Here we show that self-control capacity can be altered in healthy humans at the time scale of a workday, by performing difficult executive control tasks. This fatigue effect manifested in choice impulsivity was linked to reduced excitability of the LPFC following its intensive utilization over the day. Our findings might have implications for designing management strategies that would prevent daylong cognitive work from biasing economic decisions.
