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.
A newly discovered brain circuit allows us to focus attention on what's important in the environment and ignore other sensory stimuli.
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.
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.
Researchers have released a whole-brain projectome consisting of over 6,000 single neurons in the mouse prefrontal cortex.
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.
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.
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.
Communication between the medial temporal lobe and prefrontal cortex determines how our experiences become memories. As the brain areas mature, the precise way they interact allows for the better formation of long-term memory.
Neurexin1 deletion impacts insulin signaling and glucose metabolism in the prefrontal cortex. Researchers say increasing insulin signaling may be an effective therapeutic strategy for the treatment of ASD.
Researchers measured how brain waves travel in the prefrontal cortex during working memory tasks.
