More and more evidence is turning up to show that the brain can rewire itself, even in the face of catastrophic trauma
Neuroplasticity refers to changes in neural pathways and synapses which are due to changes in behavior, environment and neural processes, as well as changes resulting from bodily injury.
Definition: Neuroplasticity – also called brain plasticity or brain malleability is the inherent ability of the brain to change in response to experiences. It is a naturally occurring process that is ongoing, dynamic, and can change in the direction toward the positive (adaptive, appropriate) or the negative (maladaptive, inappropriate). On the positive side, learning new things, imagination, and new experiences create physical (observable and measurable) changes in the brain.
Brain reorganization takes place by mechanisms such as "axonal sprouting" in which undamaged axons grow new nerve endings to reconnect neurons whose links were injured or severed. Undamaged axons can also sprout nerve endings and connect with other undamaged nerve cells, forming new neural pathways to accomplish a needed function
There is ample raw material for neuroplasticity to occur. It is estimated that 80 billion neurons are involved in information processing (cognitive activity) and each neuron can have as many as 20,000 connections………
