Wave Neuroscience Inc. is a global leader in brain health technology and treatments. The firm comprised of doctors, researchers, parents, athletes, artists, and mental health advocates aims to advance the discipline of neuroscience daily. With different patented technologies, Wave Neuroscience Inc. provides noninvasive methods of analyzing and improving brain function. Non-invasive techniques in neuroscience can help stimulate brain activity from the surface of the head without introducing instruments into the body. One such method, transcranial electrical stimulation (TES), involves a wide range of techniques that inject strong (typically ~600–1600 mA) or weak electric current (typically 1–4 mA) into the brain to achieve neuronal depolarization or hyperpolarization. Some variants of TES include transcranial direct current stimulation, transcranial alternating current stimulation, electroconvulsive therapy, and transcranial pulsed current stimulation. Another method is transcranial magnetic stimulation, which operates on the principle of electromagnetic induction, where an electromagnet placed on the scalp generates magnetic field pulses. The magnetic field then induces a corresponding electrical current within the cortical tissue that can either hyperpolarize or depolarize neurons within the stimulation's target site. A third method, transcranial photobiomodulation, uses near-infrared light (760–940 nm) via light-emitting diodes or low-level lasers casting light onto the head to penetrate the skull and modulate brain activity. Transcranial focused ultrasound is a fourth and new noninvasive low-energy technique. It uses high-pressure waves (~250–600 kHz) to penetrate the human skull to either excite or inhibit cellular activity.
