1. A system for monitoring an electroencephalogram of a patient during administration of transcranial magnetic stimulation, comprising:

  • a transcranial magnetic stimulation (TMS) system to provide a train of pulses of magnetic energy, the train of pulses having a frequency;

    an electroencephalogram (EEG) monitoring system to monitor electrical signals, wherein the electrical signals include electrical signals having a same frequency as the frequency of the train of pulses; and

    a control system, coupled between the EEG system and the TMS system, that responds to the electrical signals provided by the EEG system and controls the TMS system;

    wherein timing of operation of the EEG system does not need to be synchronized to timing of operation of the TMS system.
