 Аннотация лекции

What is the primary motivation for behavior? Procreation? Ensuring survival of the social group? Survival of the individual? The latter requres that physiological stability and homesotatic maintenance of the organism is ensured despite environmental perturbations. Efficient regulation of internal homeostasis and defending it against perturbations requires complex behavioral strategies. However, the computational principles mediating brain’s homeostatic regulation of reward and associative learning remain undefined. Here we develop a formal definition for primary rewards, as outcomes fullfilling physiological needs. We then build a normative theory showing how learning motivated behavior is modulated by the internal state of the animal. The theory alows us to prove that seeking rewards is equivalent to the fundamental objective of physiological stability. This shows that defending physiological stability is rational from an economic point of view. We further give a formal basis for temporal discounting of reward, as it is necessary for physiologically rational behavioral patterns. Our theory also explains how animals learn to act predictively to preclude prospective homeostatic challenges, and attributes a normative computational role to the modulation of midbrain dopaminergic activity by hypothalamic signals.
