Attention-dependent attribute comparisons underlie multi-attribute decision-making in orbitofrontal cortex.

Economic decisions often require weighing multiple dimensions, or attributes. The orbitofrontal cortex FC) is thought to be important for computing the integrated value of an option from its attributes and comparing lues to make a choice. Although OFC neurons are known to encode integrated values, evidence for value mparison has been limited.

Multiattribute Decision-making in Macaques Relies on Direct Attribute Comparisons.

In value-based decisions, there are frequently multiple attributes, such as cost, quality, or quantity, that contribute to the overall goodness of an option. Because one option may not be better in all attributes at once, the decision process should include a means of weighing relevant attributes. Most decision-making models solve this problem by computing an integrated value, or utility, for each option from a weighted combination of attributes.

Identifying identity and attributing value to attributes: reconsidering mechanisms of preference decisions.

Although the orbitofrontal cortex (OFC) robustly encodes value during preference decisions, it also encodes multiple non-value features of choice options. The role of this information, and its relationship to the options' overall value remain open questions. In this opinion, we attempt to disentangle oft-studied categories of option information - identity and attributes - in the context of both classic theories of economic choice and contradicting evidence of choice biases in multi-attribute decisions.

Heterogeneous value coding in orbitofrontal populations.

Value signals in the brain are important for learning, decision-making, and orienting behavior toward relevant goals. Although they can play different roles in behavior and cognition, value representations are often considered to be uniform and static signals. Nonetheless, contextual and mixed representations of value have been widely reported.
