This means dopamine is not so much the actual reward but more the incentiviser. The release of dopamine only occurs in the wanting stage (see '''Figure 2'''), '''i.e.''' between seeing the ball (signal) and actually getting it (reward)<ref>'''Observations from the Neuroscience and Psychology Laboratory.'''

This process is ''addictive,'' once complete, the dog looks for its next trigger, that starts the dopamine release again ('''Figure 3''').

This process could proceed infinitely however within every cycle is a downward step, a [[Negative Feedback Loop|negative feedback loop]], which means every time the dog runs and gets the ball its reserve energy reduces a notch and eventually, the dog tiredness overcomes the want for another reward and it stops. | ||
