1. A system for recording of electrical signals in the presence of artifacts, comprising:

  • a stimulation electrode configured to introduce a stimulation signal;

    a recording electrode configured to receive an electrical signal;

    a blanking circuit electrically coupled to the recording electrode, the blanking circuit comprising a switch in parallel with a capacitor, wherein the switch effectively shorts the capacitor when closed;

    an amplifier electrically coupled to the blanking circuit and configured to amplify the electrical signal, wherein the amplifier has a first gain when the switch is closed and a second gain lower than the first gain when the switch is open; and

    a driver electrically coupled to the amplifier and configured to buffer the output of the amplifier, wherein;

    the blanking circuit is located between the recording electrode and an input to the amplifier.
