A new mathematical equation predicts which individuals will have more happiness and increased brain activity for intrinsic rather than extrinsic rewards. The approach can be used to predict personal preferences based on mood and without asking the individual.
White lies that are selfish in nature elicit increased activity in both the ventral and rostral medial prefrontal cortex.
Using characters from "Game of Thrones", researchers investigated what happens in the brain when people immerse themselves in fiction. The study found the more people became immersed in a story, the more they "became" the fictional character while reading. This was reflected in activity changes in the ventromedial prefrontal cortex, an area of the brain associated with thinking about one's self.
Synchronized activity between the ventromedial prefrontal cortex and temporoparietal junction improves learning and decision-making when people try to avoid harming others.
Scenes of justified and unjustified violence in movies activate different areas of the adolescent brain. Unjustified violence activates the lateral orbital frontal cortex, while scenes where violence appears justified, activates the ventromedial prefrontal cortex.
Neuroimaging reveals 'successful' psychopaths (those who can control their antisocial tendencies) have greater levels of gray matter density between the left and right ventromedial prefrontal cortex. This area of the brain is implicated in self-regulatory processes, including reactive emotions.
The medial prefrontal cortex persistently encodes value based decision variables.
Compared to peers who do not use cannabis, teens and young adults with significant marijuana use history have reduced activation in brain areas that support cognitive control and conflict resolution.
