Abstract

A system for monitoring an electroencephalogram of a patient during administration of transcranial magnetic stimulation including a transcranial magnetic stimulation (TMS) system, an electroencephalogram (EEG) monitoring system, and a control system, coupled between the EEG system and the TMS system, that responds to signals provided by the EEG system and controls the TMS system wherein timing of operation of the TMS system does not need to be synchronized to timing of operation of the EEG system. A conductive plastic electrode system for use with the EEG monitoring system is also provided.

Claims

1. An electrode system, comprising:

an electrically conductive plastic electrode cup;

a wire molded into an inner surface of the conductive plastic electrode cup; and

a coating of conductive epoxy disposed on the inner surface of the conductive plastic electrode cup.

2. The electrode system of claim 1, wherein the electrode system may be used for electroencephalogram detection.
