First-in-humans discovery reveals brain chemicals working behind the scenes during decision-making

The idea that people make decisions based on social context is not a new one in neural economic games. But now, for the first time, researchers publishing in Nature Human Behavior show the impact of the social context may spring from the dynamic interactions of dopamine and serotonin. Researchers built carbon-fiber electrodes that were implanted in patients receiving Deep Brain Stimulation surgery. The method allows researchers to measure more than one neurotransmitter at a time, revealing a dance that has never been seen before
