- The orbitofrontal cortex (OFC) in both monkeys and humans plays a key role in encoding the subjective value of options during decision-making, with evidence showing that these values can change based on recent experiences.* -
- In a study involving human epilepsy patients, high-gamma brain activity in various cortical and subcortical areas, especially the OFC, was linked to the subjective values assigned to snack foods during an auction task.* -
- The findings indicate that the OFC not only represents subjective value but also reflects context-dependent signals influenced by the value of previously offered items, suggesting that these value and context signals are represented separately in the brain.*
