The brain does come equipped with a key to those locked synapses—and we have the resilience to become radically free of our early emotional learnings.”

”Remarkably, what the brain requires to unlock and erase a particular learning follows the same three-step process in all those species: reactivating the emotional response, unlocking the synapses maintaining it, and then creating new learning that unlearns, rewrites, and replaces the unlocked target learning.

There is growing evidence of brain plasticity.  Described by Dr. Pascale Michelon, Neuroplasticity or brain plasticity refers to the brain's ability to CHANGE throughout life.  The human brain has the amazing ability to reorganize itself by forming new connections between brain cells (neurons). 

In the article Can You Rewire Your Brain to Change Bad Habits, Thoughts and Feelings?, they explain, "This key became evident in 1997, when several labs began publishing reports of a brain process that hadn’t been recognized before. This process turns off a learned emotional response at its roots, not by merely suppressing it—as in a behavioral-extinction procedure—but by actually unlocking the neural connections holding it in place and then erasing it within the nervous system. Brain researchers named this process memory reconsolidation, and went on to demonstrate how it works in nematodes, snails, sea slugs, fish, crabs, honeybees, chicks, mice, rats, and humans."
