Researchers at the California Institute of Technology have pinpointed the two brain regions responsible for managing self control. In people with poor self-control, a single brain region, the ventral medial prefrontal cortex (vmPFC) seems to decide based solely on the short term appeal of a choice, such as picking the tastier of two foods. In people with better self control the vmPFC interacts with another brain region, the dorsolateral prefrontal cortex (DLPFC), which appears to add balance by incorporating long term considerations, such as the health consequences of the two foods.
