Classification of different brain regions in terms of their activation patterns (from [18]): Cognitive regions respond equivalently to Regular and Exception Problems and respond more strongly during problem solution than during reflection on feedback.

Metacognitive regions respond more strongly to Exception Problems than Regular Problems and respond as strongly during problem solution and as reflection. Mixed regions also respond strongly to the task, but show an average of the cognitive and metacognitive patterns. See [18] or later in the text for an explanation of other regions.
