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.
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.
A new study reports reducing the strength of communication between the amygdala and prefrontal cortex helps reduce fear levels in mice.
Reducing the excitation-inhibition ratio by diminishing excitability of pyramidal neurons or increasing excitability of PV neurons led mice to spend more time engaged in social encounters. Researchers believe the excitation-inhibition balance may play a key role in autism and normal social behavior.
In the medial prefrontal cortex, loneliness is associated with a reduced representational similarity between the self and others. Feeling socially disconnected may be mirrored by a self-representation of being a "loner."
Study links common steroid used to prevent premature birth to impaired cognitive function in offspring.
Researchers reveal the role the prefrontal cortex plays in emotional processing and emotional suppression.
Researchers explore the effect psychedelics have on the brain and how they are effective at treating depression.
Novel experiences dampen previous memory representations in the hippocampus and prefrontal cortex, facilitating flexible strategy encoding in mice.
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.
