Neuromodulation is a field of research that focuses on the use of techniques to directly or indirectly alter the function of the nervous system in order to treat neurological and psychiatric disorders. This can involve the use of electrical stimulation, chemical agents, or other methods to modulate the activity of neurons in the brain or peripheral nervous system. Neuromodulation has shown promise in treating conditions such as chronic pain, movement disorders, epilepsy, and mood disorders. Researchers in this area aim to better understand the mechanisms of neuromodulation and develop more effective and personalized treatment options for patients.
