Neuronal signals for reward risk in frontal cortex

Abstract:

Rewards can be viewed as probability distributions of reward values. Besides expected (mean) value, a key parameter of such distributions is variance (or standard deviation), which constitutes a measure of risk. Single neurons in orbitofrontal cortex signal risk mostly separately from value. Comparable risk signals in human frontal cortex reflect risk attitudes of individual participants. Subjective outcome value constitutes the primary economic decision variable. The terms risk avoidance and...
