Highlights ► Economic theories suggest that it is as if values of rewards are mapped on a common scale for comparison. ► A few brain areas appear to encode values on a neural common scale. ► A new meta-analysis suggests that the main area representing value on a common scale is a subregion of the vm...

Description
Summary:	Highlights ► Economic theories suggest that it is as if values of rewards are mapped on a common scale for comparison. ► A few brain areas appear to encode values on a neural common scale. ► A new meta-analysis suggests that the main area representing value on a common scale is a subregion of the vmPFC/OFC. ► We review a neurobiological foundation for standard economic theory. ► This suggests a tool for measuring preferences.
