For over a decade, neuroscientists have been trying to figure out how neurogenesis (the birth of new neurons) and neuroplasticity (the malleability of neural circuits) work together to reshape how we think, remember, and behave.
From a psychological standpoint, the latest UAB discovery presents the exciting possibility that when adult-born neurons weave into existing neural networks that new memories are created and older memories may be modified. During this state-of-the-art study on mice, neuroscientists at the University of Alabama at Birmingham (UAB) found that the combination of neurogenesis and neuroplasticity caused less-fit older neurons to fade into oblivion and die off as the sprightly, young newborn neurons took over existing neural circuits by making more robust synaptic connections.
Through neurogenesis and neuroplasticity, it may be possible to carve out a fresh and unworn path for your thoughts to travel upon. One could speculate that this process opens up the possibility to reinvent yourself and move away from the status quo or to overcome past traumatic events that evoke anxiety and stress. Hardwired, fear-based memories often lead to avoidance behaviors that can hold you back from living your life to the fullest.
new research by Linda Overstreet-Wadiche and Jacques Wadiche that pinpoints the specifics of how adult-born neurons modify existing neural circuits. This is fascinating stuff!
