Solution Overview

Problem

Existing open-loop AVS brainwave entrainment devices are limited by using single frequency entrainment, which may not effectively address concurrent brainwave activity across multiple frequency bandwidths, such as delta, theta, alpha, beta, and gamma, and ignore potential benefits of cross-frequency coupling for addressing complex mental states.

Innovation Solution

The use of electromagnetic radiation therapy devices that oscillate between distinct polarization states, such as between nonpolarized and polarized, or between different types of polarization, to provide a composite waveform that can entrain brainwaves in multiple frequency regimes, potentially enhancing the effectiveness of brainwave entrainment by mimicking native neuronal processes.
