Researchers uncover a key role of medial prefrontal cortex corticotropin-releasing factor interneurons for bidirectionally controlling motivated behavioral styles under stress. The findings could help in the development of new treatments for PTSD.
Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain.
Study finds EEG features may not always be accurate in being able to capture the level of consciousness in patients under anesthesia.
Study identifies distinct neural processes that occur when we make decisions for the benefit of ourselves and of others.
Study identified the neural correlates of fear during dreaming and reports similar areas are activated when experiencing fear during wakeful states.
A network linking the medial prefrontal cortex and brainstem plays a critical role in the development of compulsive drinking disorder and is a driver for its expression.
To accurately perceive another person, your neural representation of that person has to match the pattern in the persons' brain when they think about themselves.
Deep sleep restores the medial prefrontal cortex mechanisms that restore emotion. This lowers emotional and physiological reactivity, preventing the escalation of stress and anxiety.
Neural pathways for learning differ depending on how each person has learned a new skill.
Researchers have identified a comprehensive circuit mechanism that governs how emotional states can influence movement through connections in the basal ganglia. The mechanism represents a way in which emotional states relate to changes in action control in depression, anxiety, and OCD.
S1PR3, a receptor found on the surface of brain cells, may play a key role in stress resilience. Veterans with severe PTSD symptoms had lower levels of the S1PR3 protein in their blood than peers without the disorder.
A positive correlation has been identified between prosocial and rebellious behaviors in teens. The more risk taking behaviors a teen exhibited, the more likely they were to act prosocially. The findings suggest the same developmental processes are at work for both types of behaviors. Also noted was faster brain development in the medial prefrontal cortex predicted a decrease in rebellious behavior.
