Abstract: Technologies that stimulate the mammalian central nervous system are described. A method includes: (a) causing a pair of glasses to be worn by a user, where the pair of glasses hosts/interacts with a processor, a first light source, a second light source, a first sound source, and a second sound source; (b) causing the processor to read sets of parameters that include information regarding base frequencies, variability, frequency ranges, and time ranges, where the frequency ranges are positively and negatively off the base frequencies; and (c) causing the processor to request the light sources to (i) flash light to visual fields (left/right) of each eye according to selected frequencies for a duration of time and to (ii) pulse sound to the each ear according to selected frequencies for a duration of time such that an audio-visual entrainment (AVE) occurs that causes neuron and the glia to respond dynamically to the AVE.

Abstract: This discloses enables various technologies for audio-visual entrainment with breathing cues for managing heart rate variability.
