ABSTRACT:
A self-preparing electrode, suitable for EEG mapping, includes a metallic cylinder separated by a dielectric cylinder from a socket for a probe assembly. The probe assembly is preferably a tulip probe removably held by the socket which is connectable to an inner conductor of a coaxial cable. The metallic cylinder includes a cavity into which the tip of the tulip probe is partially depressed when the probe assembly and shell are placed on the skin of a patient. The tip of the tulip probe has multiple points which penetrate the dead skin layer and make electrical contact with the blood-rich skin layer of the patient. The electrode is held in place by straps attached to the shell of the electrode.
