A differential neural response in the human amygdala to fearful and happy facial expressions
Article Abstract:
The left human amygdala shows a greater neural response to facial expressions of fear than to those of happiness indicating that the amygdala is involved in regulating human social behavior. This response demonstrates a significant interaction with the intensity of emotion. It increases with increasing fearfulness and decreases with increasing happiness. The findings support psychological data based on multidimensional scaling, indicating that the facial expressions of fear and happiness are at opposite ends of a similarity spectrum.

Evidence for striatal dopamine release during video game
Article Abstract:
A new study demonstrates that human brains release dopamine while playing video games that involve shooting enemy tanks. The success of the player mediates the amount of dopamine released in the dorsal and ventral striatum. The role of the dopamine release under these circumstances is unknown, but it shows, for the first time, that certain behavioural conditions prompt the release of dopamine in humans.
