Over the years, Vielight's focus shifted towards the development of unique photobiomodulation devices which enhance cognition and performance, among other things. Their team has since evolved into a formidable team of engineers, scientists, and business professionals dedicated to taking the technology to as many people as possible. My guest on this show, Dr. Lew Lim, is an engineer with additional diplomas in Medical Neuroscience and Business and Accountancy. Have you ever seen me wearing a crazy, laser-light helmet on my head, with red-flashing nasal probes shoved into my nostrils, and thought... ..."What the heck is that, and why would someone ever choose such a horrific fashion statement?" But stick with me here because there's actually something to the science of this so-called use of "photobiomodulation." A lot of something and a lot of science. The basis of all your thoughts, behavior, and emotions is the communication between your neuronal networks. This interaction leads to the formation of neural electrical signals known as brainwaves. Brain stimulation via photobiomodulation stimulates neuronal mitochondria, which increases cellular energy levels. This results in improved efficiency in neural signaling and communication. The "helmet" red light technology I wear - which I don three to four times per week for 25 minutes - is the first in the world to demonstrate the ability to modulate and alter brainwaves using NIR electromagnetic (light) energy, measured through EEG. Delivering pulsed near-infrared (NIR) light energy into the brain’s Default Mode Network (DMN) upgrades brain capability, increases longevity, and improves physiological health. Microchip-boosted cold LED diodes in this setup - made by a company called "Vielight" (use code GREENFIELD to save 10%) - can safely maximize energy transmission into the brain, and intranasal photobiomodulation technology is used for ventral brain stimulation. Transcranial-intranasal systems like this enable comprehensive, non-invasive, and safe brain photobiomodulation. In fact, the Vielight Neuro is the world’s most-researched brain photobiomodulation device. It delivers 810 nm near-infrared (NIR) energy to the brain’s Default Mode Network (DMN) via four transcranial LED modules and a nasal applicator. Vielight Neuro transcranial-intranasal technology offers an unparalleled advantage for improving mental acuity and neuromodulation. Neuro Alpha causes alpha wave activity that correlates with the alpha flow state, mental calmness, and stress reduction. You can read a published abstract of a study with the Vielight Neuro Alpha device on Alpha brain waves here. Neuro Gamma wave frequency correlates with energization, problem-solving, and focus. You can read a published study with the Vielight Neuro Gamma device on Gamma brain waves here. The Vielight X-Plus targets vital structures within your body: the cerebellum, thymus gland, and nasal vascular area. It can be combined with the Vielight Neuro as a complete brain-systemic photobiomodulation system. The technology of Vielight dates back to 1995 in Silicon Valley - when the founders, Dr. Lew Lim, who first joined me on the episode How To Use Low-Level Light Therapy and Intranasal Light Therapy For Athletic Performance, Cognitive Enhancement & More - and a group of engineers explored the potential of intranasal photobiomodulation. Intranasal photobiomodulation devices were commercially developed in 2003 which were later trademarked as “Vielight” when the company was incorporated in 2011.
