Modell einer Elektrode zur multiaxonalen Reizung des Nervus acusticus

Summary

An electrode arrangement is described, which allows an isolated stimulation of 25–50 singular axons: By laser beams a small ceramic plate got 25–50 perforations through which glass isolated platin wires were so fixed that they end like a brush. Only the tips of the “hairs” are not isolated. The diameter of the electrodes is approximately 10 μm, the length ranges between 0,5 and 1,5 mm. This electrode system is enough stabile to be pressed into a hard boiled egg without being damaged.
