A new study reports high testosterone levels is linked to lower sensitivity when faced with negative emotions.
A new study reports traumatic experiences can alter the brain, leaving people more vulnerable to psychological problems.
When viewing OCD related images, those with the disorder had increased distress and higher levels of activity in emotion related brain regions than their siblings who did not suffer from OCD, researchers report.
The dorsomedial prefrontal cortex plays a critical role in mapping out personal actions and outcomes as well as responding to the actions of others.
Researchers discovered a part of the brain involved in future behavioral changes, the dorsomedial prefrontal cortex, had greater activation when smokers were exposed to anti-smoking messages with stronger arguments as opposed to weaker arguments.
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.
Virtual reality is helping researchers uncover some of the secrets of anxiety. Using VR, study participants were able to distinguish between safe and dangerous environments in a game. However, brain scans of those with anxiety showed increased activity in the insula and dorsomedial prefrontal cortex while in a safe zone, indicating their brains were associating the safe environment with threat or danger.
Researchers report the interaction between two regions of the prefrontal cortex may underlie our motivation to cling to a desirable notion about the future.
Researchers have uncovered the neural mechanism underlying rumination. The study reports when rumination occurs, coupling between the core and medial temporal lobe subsystems of the default mode network becomes elevated, while coupling between the core and dorsomedial prefrontal cortex decreases.
A new study reports the reward system in our brains may affect our judgments.
In men with a history of childhood trauma, oxytocin reduced the activity within the amygdala and cravings for cocaine. Women who were addicted to cocaine and had experienced childhood trauma showed an increase in amygdala activity following exposure to oxytocin.
