Specific inhibitory neurons in the prefrontal cortex appear to become persistently activated following acute stress. The findings may pave the way for the creation of more targeted therapeutics for stress.
From age-related brain shrinkage that may affect our social cognition, to feeling more confident in our own skin, researchers investigate why older people appear to lose their "filter" when it comes to some social interactions.
The fewer slow brain waves that occur in the right prefrontal cortex during sleep, the more likely a person is to indulge in risk-taking behaviors.
Researchers have released a whole-brain projectome consisting of over 6,000 single neurons in the mouse prefrontal cortex.
Information about new experiences is retained by being tied to pre-existing activity patterns in the brain. Memory is acquired when the patterns are connected to each other across brain regions via transient bursts of activity.
The HDAC9 enzyme appears to play a critical role in learning and neural communication. Decreased expression of HDAC9 in the hippocampus and prefrontal cortex has been noted in patients with Alzheimer's disease. Researchers say HDAC9 may be a regulator of synaptic plasticity.
A newly discovered brain circuit allows us to focus attention on what's important in the environment and ignore other sensory stimuli.
A specific set of socially tuned neurons fire across multiple regions across the prefrontal cortex and the amygdala at different times during mutual eye contact. The brain regions are recruited to compute selective aspects of interactive social gaze, suggesting the importance of a more contemplative role during social gaze interactions.
Both genetics and environmental factors contribute to socioeconomic status' impact in an interplay with effects that spans several areas of the brain.
Actively forgetting a negative experience may help to prevent bad memories from constantly intruding on a person's awareness and halt rumination.
Researchers reveal the role the prefrontal cortex plays in emotional processing and emotional suppression.
