title: A glass-insulated "Elgiloy" microelectrode for recording unit activity in chronic monkey experiments.
abstract: A glass-coated microelectrode made of a stiff cobalt--nickel alloy is described. The thickness of the glass coating and the length of the uninsulated tip can be varied as desired. The electrode is stiff enough to insert through the relatively tough dura of the monkey in chronic experiments. Further, the recording site can be marked by electrolytic deposition of iron and the Prussian blue reaction.
