On the waterfront: predictive and reactive regulatory descriptions of thirst and sodium appetite.
The concepts of homeostasis and regulation are discussed and examples are given in which current regulatory models of ingestive behavior inadequately predict or explain the observed phenomena. The implications of this for the choice of experimental paradigms, and the interpretation of neurobiological data obtained therein, are discussed. Paradigms that allow the expression of behavioral strategies and learned responses may be biologically more relevant than the more popular but highly constrained "physiologic" paradigms.
