In the case of nutrition, for example, S∗ can represent a desired reserve of “nutritional well-being,” while δ represents the body’s physiological demands on this reserve, and q represents the rate at which the reserve is replenished. On the behavioral side, β can be interpreted as representing the beta brain’s desired response in q to a change in the actual value of s. This response, however, is tempered by the coefficient γ .
