| Research Abstract |
We developed a new stimulator for intraoperative visual evoked potentials (VEPs). The new stimulator was consisted 10 light emitting diodes, which has 40 times luminescence than the old one. Also its basic plate was made of silicon to be soft enough. By using new stimulating diodes, stable VEP could be recorded even if the scalp was reflected. At present, influence of anesthetic agent is evaluated.
Concerning to optic nerve evoked potentials (ONEPs) elicited by electrical stimulation of the optic nerve, we confirmed to be able to record stable waveforms in animal experiments. After cutting the optic nerve, the waveform was disappeared. At present, we are trying to develop new stimulating electrodes to stimulate the optic nerve safely.
