summaryThe "neuro-economics" research program postulates that subjective values underpinning choice behavior can be identified in neural signals. In this talk, I will first provide evidence that subjective values are indeed reflected in a dedicated brain system, with the ventromedial prefrontal cortex as a key component. Then I will highlight some properties of this brain valuation system (BVS) that complicate the decoding of subjective values but explain some deviations from rationality, such as preference instability. Finally, I will illustrate some situations in which the construction of subjective values involves other brain systems: for instance the episodic memory system when values are assigned to imagined and not perceived items, and the mirror neuron system when values are derived from the observation of other agents. Interactions between the BVS and these other systems might account for psychological phenomena such as choice impulsivity (why we succumb to the temptation of immediate pleasures) and mimetic desire (why we want what the others want).
