When Eyes Meet, Neurons Start to Fire

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.

Age and Alzheimer’s Related Brain Decline Linked to Little-Studied Enzyme

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.

Memory Is Formed Through Rewiring of Global Network Among Pre-existing Local Neuronal Ensembles

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.

Do We Really ‘Lose Our Filter’ as We Age?

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.
