A precision multichannel cuff electrode optimized by simulation and experiment

The parameters influencing single end and differential en passant extracellular recordings were investigated using two independent simulation methods. The results were compared with measurements from experimental electrodes. The effects of electrode size, electrode distance and leakage can thus be understood and the experiments agree with the simulation results. This led to the optimation of a novel en passant electrode producing very narrow signals with very high reliability. The electrode is used for multichannel recordings in a velocity selective recording system.
