摘要：
Method and apparatus for optically stimulating neurons of a plurality of auditory nerve pathways of a person to provide auditory sensations for the person including generating a plurality of pulsed light signals having one or more successive pulses； delivering the plurality of pulsed light signals to one or more auditory nerve pathways of the cochlea of the person； selectively controlling the plurality of light signals to optically stimulate and trigger nerve action potentials (NAPs) in the one or more auditory nerve pathways. In some embodiments of the present invention, pulse-repetition rate and peak pulse power are held constant, while pulse width is modulated to evoke a sufficient dynamic range of NAPs (i.e., different NAP strengths), thus encoding sound-loudness information for the listener.
