It is the reward, the goal, the destination, the positive and the negative, the yin-yang, the imbalance seeking balance and it's the cyclic nature of things that keeps life going. Turning the light on brings into focus an out of focus array of possible matches for the response that we are desiring. Too much input, on the other hand, makes demands on our executive decision making center that has to prioritize stimulus - response activity into a correct sequence necessary for coordinated movement.
