摘要
A method and system of readily specifying a wide range of temporospatial patterns of electrical stimulation waveforms that can be used by an implantable cochlear prosthesis. Such stimulation patterns and waveforms can thus be readily tested by an audiologist in the process of fitting the cochlear prosthesis, allowing desirable patterns of pulsatile stimuli of almost arbitrary complexity to be modulated in real-time by the acoustic signal to produce useful perceptions of sound in otherwise deaf patients. The cochlear prosthesis includes two main components: (1) an external system, and (2) an implantable system. The external system includes electronic circuitry, typically including a microprocessor, that converts sensed acoustical signals to electrical signals and processes the electrical signals in accordance with a desired speech processing strategy. The present invention facilitates the definition of complex stimulation waveforms to be used as part of the selected speech processing strategy. In a preferred embodiment, the stimulation patterns and waveforms are specified in a template table, the rows and columns of which define time intervals and stimulation sites. Alternatively, the stimulation patterns and waveforms may be specified in a list of spatial/temporal events.
