Conversation: Serpentine Gallery ~ Edge: Map Marathon
An expected value map that my laboratory generated in 2005, in 2 and 3 dimensions. The map illustrates brain regions whose activity (or oxygen utilization) increases proportional to the amount of money people anticipate making (and combines data from fourteen subjects). From a neuroscience standpoint, it is interesting to note that these regions overlap the ascending projection areas of midbrain dopamine neurons. Researchers are now using activity in some of these regions to predict subjects' upcoming choices (e.g., in investment or shopping scenarios).
