STIMULATION METHOD FOR MAINTAINING RESPONSIVENESS OF CELLS

摘要

A method of neural stimulation is described for maintaining the responsiveness of electrically excitable cells to repeated electrical stimulation. A stimulating signal (23) is applied to the electrically excitable cells. The stimulating signal is repeatedly applied (26, 29, 32, 35) with a progressively increasing signal strength. A quiescent period (44) may be interleaved between bursts (43, 45) of stimulation. The electrically excitable cells may be retinal cells.
