How is value represented in the brain?
Recent advances in brain scanning technology have allowed experimenters to go beyond the simple "blob-ology" of identifying which areas of the brain are active when an individual is offered money or rewards. We are now able to investigate the specific patterns of activity within these regions, looking with more detail at the magnitude of neural responses to different sums of money and items of differing value. Our research shows that rather than representing the objective financial value of the current offer, this brain activity correlates with the offer's relative rank within values used in the task. We will also present evidence from both behavioural and brain imaging studies investigating how recently viewed items are selected for these rank order comparisons I will also present a summary of Neuroimaging findings on the more general topic of how is value represented in the brain?
