Venue: Building A2 4, Room 2.16 (SRIIa)

Topic: Cognitive control as a process of prediction and evaluative function

To err is human.  People make mistakes and are able to recognize their mistakes.  Furthermore people can learn when they are likely to make mistakes in the future, and sometimes they can avoid altogether situations in which things are likely to go wrong.  The medial prefrontal cortex is a key brain region involved in recognizing and avoiding mistakes.  In this talk I describe a recent computational neural model of how mistakes are anticipated and recognized.  The model builds on the simple notion that the brain forms expectations about how things should work out and then compares those expectations against what actually happens (or fails to happen).  I show how the model accounts for a variety of behavioral, neurophysiological, and neuroimaging data from humans and monkeys.  In the remainder of the talk, I present a series of human fMRI studies aimed at testing the model predictions.
