What is brain plasticity and why does it matter?

It’s been a while since scientists first noted that the brain is plastic. This doesn’t mean it’s made of plastic. Instead, neuroplasticity – or brain plasticity – is the ability of the complex organ to change throughout life. The central nervous system can adapt or change after some external stimulation, or the same principle used for restoring brain damaged areas and to heal from injury, according to neuroengineer Dr. Curtis Cripe.


Brain plasticity occurs at the beginning of life, a time when the young brain begins to organize itself. It also takes place during brain injury to compensate for lost functions or help remaining ones, and through your adult years whenever you learn or memorize something new. The scientific consensus is that the brain never stops changing via learning.

Studies of neural connections also indicate that many damaged cells can lead to new connections based on a process known as synaptic reorganization, forming the basis for brain plasticity. Dr. Curtis Cripe noted that these concepts require the brain as well as the nervous system to be externally stimulated to make development or recovery – such as from trauma or addiction – to occur.

This emerges as a very important process in light of scientific findings that under the right circumstances, neuroplasticity can help an adult mind grow. While specific brain machinery can break down with age, people can still tap into plasticity and refresh this machinery. This can be done through targeted brain exercises as well as retraining the brain back to health at the onset of a cognitive condition such as schizophrenia and dementia.

Neuroengineering: A Quick Overview

Neuroengineering marries the different fields of neuroscience, device development, computation, and mathematics, and is an exciting modern venture into science and technology. It has generated plenty of excitement not only for developing interfaces between the brain and computers but also for mostly untapped potential in developing treatments for neurological conditions such as strokes and epilepsy. It combines technologies and algorithms with experimental research to accomplish the following.

Develop devices and computing: This is to assist patients with neural disorders, which affects almost 1 billion people around the globe.

Reveal how neural systems perform computations: This is one of the biggest challenges that confront science today.

Inspire new technologies and algorithms: Through reverse engineering living neural systems, scientists in this field can produce more innovations, such as robotics.

Educate younger scientists and engineers: It can pave the way for transcending the traditional limits and boundaries of science, technology, engineering, and mathematics (STEM).

Perhaps one of most memorable examples of neural engineering is the bionic arm, where the DEKA Arm is currently underway in clinical trials out of hopes of providing amputated U.S. soldiers with an artificial limb that is way more advanced than the basic hook used since the World War II. The DEKA Arm recognizes signals coming from the brain and relays signal back to the human organ.

A closer understanding of how neurons work could discover ways to stimulate or disrupt the neurocircuitry. This way, implantable devices akin to pacemakers could be used for controlling nervous system conditions such as depression and Parkinson’s disease.

With the diverse array of disciplines it incorporates, neuroengineering could offer pioneering insights into understanding further prevalent brain and nervous system disorders and other neurologic deficits affecting millions worldwide.
