Abstract :
Electrical stimulation of the optic nerve with penetrating electrode array for visual recovery had been proposed by C-Sight group. This paper presents the latest progress of various component parts of visual prosthesis, including design and testing of neural stimulator, fabrication of multi-channel flexible microelectrode array. According to the experiment data, the linearity between practical stimulator output and the setting parameters has been validated. The temporal properties of EEP evoked by optic nerve stimulation with penetrating electrodes will be introduced briefly according to in vivo electrophysiological study.
