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.
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.
Researchers report ADHD and conduct disorder exhibit similar, overlapping changes in the brain.
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.
A new Scientific Reports study links structural changes in the teenage brain to behavioral changes when it comes to understanding the intention of others.
A new report in Science identifies a neural circuit in the dorsomedial prefrontal cortex of mouse brains that may play a key role in social dominance. Using optogenetics, researchers were able to target neurons in the dmPFC to help boost a mouse's chance of 'winning' in an aggressive encounter.
