[[OFC ]] is predominantly associated with ([[learning|learned]]) [[value|valuation ]] of (reinforcing) stimuli, but there is evidence of a distinct process in [[ACC ]] (which projects anatomically to premotor regions) of [[value|value encoding ]] for reinforced actions, and ACC sulcus may be required for learning of [[action ]] values<ref>Kennerley SW, Walton ME, Behrens TEJ, Buckley MJ, Rushworth MFS.
