It seems that that the vmPFC calculate the valuse of different options that are comming from the [[dlPFC]]<ref>[http://www.rnl.caltech.edu/publications/pdf/hare2009.pdf Self-control in decision-making involves modulation of the vmPFC valuation system.

The vmPFC is also connected to [[self control]]<ref>[http://www.rnl.caltech.edu/publications/pdf/hare2009.pdf Self-control in decision-making involves modulation of the vmPFC valuation system. Todd A Hare, Colin F Camerer, Antonio Rangel(2009) Science 324 (5927) p. 646-8] ([http://www.talyaron.com/wiki/index.php?title=%D7%9E%D7%90%D7%9E%D7%A8:_Self-control_in_decision-making_involves_modulation_of_the_vmPFC_valuation_system summery])</ref>. Patients with damage to their ventromedial prefrontal cortex (vmPFC) are less averse to uncertainty than healthy counterparts<ref>Hsu M, Bhatt M, Adolphs R, Tranel D, Camerer CF. Neural systems responding to degrees of uncertainty in human decision-making. Science. 2005;310: 1680.</ref><ref>Shiv B, Loewenstein G, Bechara A, Damasio H, Damasio AR. Investment behavior and the negative side of emotion. Psychological Science. 2005;16: 435– 439.</ref>. So it seems that vmPFC inhibit inhibits impulsive behiviour.
