A new neuroimaging study reveals people who consider themselves to be egotistical have no increased activity in the ventromedial prefrontal cortex when they think about the distant future. By contrast, altruistic people have increased activity in this region when asked to consider the consequences of the distant future.
According to researchers, when people are aware they are being observed, brain areas associated with social awareness and reward activate a part of the brain that affects motor control, helping them to perform better at skilled tasks.
Researchers implicate the hippocampus in conceptual memory formation. The study reveals activity within the hippocampus and ventromedial prefrontal cortex is consistent with the retrieval of new concepts.
University of Oregon researchers report those who write online journals that note feelings of gratitude develop an increase in altruism.
A new study reveals chronic cocaine users have a global impairment of the ventromedial prefrontal cortex.
Substance addiction modifies they way a mother's brain responds to her own child, a new study reports. Researchers found key reward regions of the brain appear to shut down in response to their own infant's smiles in mothers with addictions.
Taking a mobile neuroimaging system on the road to prisons, researchers look at the brain activity of those considered to be psychopaths and discover their brains are wired in a way that leads them to over-value immediate rewards while neglecting future consequences.
