The NeuroVIZR® app is the companion to The NeuroVIZR® device and together function as a form of brain exercise, cleverly disguised as entertainment. By utilizing light and sound experiences, the app when used with the device, provides an enjoyable and engaging way for individuals to improve their brain function. In essence, the NeuroVIZR® is more than just a fun distraction - it is a tool that encourages individuals to actively engage and challenge their cognitive abilities. Brain Engagement is a novel approach to neuroplasticity that differs from Brain Entrainment. Brain Entrainment relies on the Frequency Following Response, which is the brain's ability to follow the frequency of a repeating signal, such as a light or tone. Brain Engagement, however, aims to signal the brain in a way that allows it to adapt and change more easily by providing it with constantly changing information while also helping the brain make predictions. This approach is a new and evolving field of study, with technology being used to apply these concepts to neuroplasticity. How it works? The NeuroVIZR® LED panel produces three simultaneous dimensions of light messaging to create a powerful and mesmerizing experience. MACRO patterning, MESO body pulsing, and cascades of MICRO flickering produce a satisfying First Language brain interaction. The “First Language” is a new and novel term describing the primal capacity of human beings to directly experience and gain knowledge at a pre-intellectual level when awareness is turned towards the subtle states of consciousness and their internal sensory expressions. The ability to compose and adjust three distinct yet integrated levels of light signaling simultaneously yields a unique and vibrant visual messaging experience. Each group of light signaling is effective in its own right, so when combining them, the information output is drastically enhanced, much like combining three musical instruments into a jazz ensemble. Collections Better Sleep – With early, mid-day, and evening options, our sessions are designed to regulate your Circadian Cycle for optimal rest. Brain Gym – Our Light/Sound experiences target specific aspects of healthy brain functioning, making it easier to achieve the desired effects during Brain Gym sessions. Mind States – Each session is intentionally designed with a specific theme, purpose, or intent, allowing you to experience positive short-term Mind states while establishing long-term Mind traits through neuroplastic changes in the brain.
