Paying attention to reality, to what you are actually doing in the moment, maximizes the flow of information into your brain. It maximizes dopamine’s ability to make new plans, because to build models that will accurately predict the future, dopamine needs data, and data flows from the senses. That’s dopamine and H&N working together. When something interesting activates the dopamine system, we snap to attention. If we are able to activate our H&N system by shifting our focus outward, the increased level of attention makes the sensory experience more intense.
