This study examines neuronal activity in the orbitofrontal cortex of rhesus monkeys during trinary economic choices, finding that value encoding and risk attitude are reflected in neural activity consistent with economic theory assumptions.

This study shows that the left superior frontal sulcus selectively affects perceptual decision-making but not value-based decisions using fMRI, TMS, and computational models.

The paper shows that individual risk aversion in financial decisions stems from noisy perception of numerical magnitudes rather than subjective valuation.
