Research reveals brain pathway that signals when we have made a mistake and facilitates better future decision-making

The Nobel prize winning physicist Niels Bohr once said, “An expert is a (person) that has made all the mistakes that can be made in a narrow field.” This idea, that to master a skill we must learn from our mistakes and avoid making them in future, has long been recognized; however, the brain mechanisms and pathways that control this ability have been poorly understood.
