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 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.

Researchers have investigated whether the body is truly disconnected from the external world during sleep. To do so, they focused on how heartbeat changes when we hear different words during sleep. They found that relaxing words slowed down cardiac activity as a reflection of deeper sleep and in comparison to neutral words that did not have such a slowing effect. This discovery sheds new light on brain-heart interactions during sleep.

New research used brain scanning technology to understand the effect of advertisements that try to sell products with talking versions of themselves. The work suggests that that anthromorphic displays lead to different cognition, and that buyers are likely to spend up to 20 percent more on more complex products promoted in advertisements that anthropomorphizes the product.
