Open the CIPO recordAbstract From the Canadian patent
An apparatus and method for transmitting prosthetic information to the brain contains an array of sensory elements that receive energy from an external stimulus and process those signals via neural filters and neural waveforms to produce a pulse or 'spike' train that is temporally encoded with information that is functionally related to the external stimulus. The simulated spike trains, when applied to an appropriate area of the brain produce perceptions that are functionally related to the sensed external stimuli so that a subject can discriminate between different spike trains representative of different external stimuli.
