Title: “Using information over multiple time frames in anterior cingulate cortex to guide changes in behavior”

By Prof. Matthew RushworthDepartment of Experimental Psychology, Oxford University, matthew.rushworth@psy.ox.ac.uk

Abstract:  Decisions are guided by expectations about the values of future choices and these expectations are, in turn, based on past experience. The anterior cingulate cortex contains information about recent reward history based on information acquired over multiple time scales.  Expectations of the value of future choices are calculated simultaneously on the basis of these timescales and used to guide decisions in different ways depending on the nature of the current environment.  This has an advantage in that it allows flexible decision making based on estimates of what future decision values might be.
