But we were saying it rules our emotions, too – and that the barricade that psychology had erected between reason and emotion has no basis in fact.

In short, the brain has the power to recruit healthy neurons to perform the function of the damaged ones. Neuroplasticity enables the brain to reassign jobs.

In this case, that change is the ability to maintain laser-sharp concentration with less and less activity in the brain’s attention circuit.
