Neurostimulation is the intentional modification of nervous system activity through invasive (e.g., microelectrodes) or non-invasive means. Electromagnetic approaches to neuromodulation are commonly referred to as "neurostimulation." Neurostimulation technology has the potential to improve the quality of life for those who are severely paralyzed or have profound losses to various sense organs, as well as the long-term reduction of severe, chronic pain that would otherwise necessitate continuously (around-the-clock), high-dose opioid therapy (such as neuropathic pain and spinal cord injury).

Neurostimulation technology involves the use of microelectrodes to activate elements of the nervous system. It involves the use of a neurostimulation device – a battery-powered stopwatch-sized device – which is surgically implanted in the brain and delivers electric signals at scheduled time intervals to the nervous system. These electric signals develop tingling sensations (paresthesia) in the damaged nerve and helps chronic pain and neurological disorders.
