Abstract: The generation of alpha waves in a mammalian subject may be stimulated through a process of measuring a wave-from produced by the electrical activity of the subject's brain, analyzing the wave-form to determine changes in its frequency, and delivering audio and visual stimulation to the subject, each at a rate selected to vary the frequency of the wave-form until any alpha state is achieved. The rate may be selected by the subject, by a therapist, or may be varied automatically through a feedback mechanism.

Abstract: The parasympathetic nervous system of a mammalian subject may be stimulated by massaging a portion of the subject's body by applying a cyclical pressure, during which the subject is encouraged to time its breathing to the massage cycle so as to achieve respiratory sinus arrhythmia. Before, during, or after the massaging step, pulses of light are delivered to the subject's eyes and pulses of sound are delivered to the subject's ears so as to achieve audiovisual entrainment of the subject's brain waves.
