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.
