Electrical Brain Stimulation to Treat Neurological Disorders

WithBahman Zohuri, Patrick J. McDaniel

Neurological disorders with symptoms such as chronic pain, depression, and insomnia are widespread. The brain communicates both chemically and electrically; however, recent advances within the neurosciences have led to a resurgence of interest in electrical stimulation to modulate brain functioning in health and disease. The player to the electrical stimulation field is transcranial Random Noise Stimulation. Transcranial magnetic stimulation is a noninvasive method to excite neurons in the brain: weak electric currents are induced in the tissue by rapidly changing magnetic fields. The brain’s electrical charge is maintained by billions of neurons. Neurons are electrically charged by membrane transport proteins that pump ions across their membranes. Quantitative electroencephalography is a method of analyzing the electrical activity of the brain to derive quantitative patterns that may correspond to diagnostic information and/or cognitive deficits. Magnetoencephalography is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers.
