Like musical sounds, your brain displays different waveforms depending on your state of mind. For example, when you are concentrated on a challenging task, gamma waves may kick in to help with attention and mental processing.

With more than 600 neurological diseases and around 450 million people in the world affected by mental or neurological disorders [1], there’s no denying that now is an exciting time for neuroscience to move from science to real-world applications. A growing area is neuromodulation.

The global neurostimulation devices market size was valued at nearly $4.4. million in 2018 and is projected to reach $11.2 million by 2026 [2].


Neuromodulation is the process by which the brain activity is altered by a stimulus. You see, your thought, emotion, and behavior are controlled and processed in the brain through neural communication, where neurons send electrical messages to and from different regions of the brain to relay critical information. These neuronal oscillations are known as brain waves.

Depending on what you are doing at a time, the state of your brain activity differs. The synchronization and balance of such activity help optimize brain performance and wellbeing.

Targeted Delivery 

There are three kinds of neuromodulation mechanisms, which are electrical current, magnetic fields, and light stimulation. Researchers are now looking into the therapeutic potential of stimulating neurons using light (brain photobiomodulation or tPBM) instead of electrical or magnetic field stimulation. Unlike electrical and magnetic stimulation that spread through tissue and cannot be focused, tPBM has the advantage to offer pinpointed, focused stimulation.

A Brief History 

Neuromodulation was first used for treatment in 1967, in the form of electrical stimulation for pain. The realization that damage to the nervous system can cause chronic pain opened up new treatments, which include neuromodulation.

Now more than 50 years later, neuromodulation is a new class of therapy that treats the nervous system itself. The technology has expanded beyond treating pain and has grown to include magnetic field stimulation and light stimulation.
