The brain responds to flashing light, and will mimic the frequency of the flashing light. This is called entrainment. The AVE is a device that not only will entrain your brain into a desired state (meditation, mood enhancement, focus) but will increase cerebral blood flow and the amount of neurons firing as well as their synchronicity. In addition, the AVE has an audio component to pair with the flashing light, as well as cranial electrical stimulation (CES).
