A method for providing stimulation of living tissue may include generating electrical pulses onto multiple output channels to a plurality of electrodes each corresponding to one of the multiple output channels. The method may also include disconnecting the plurality of electrodes from recording amplifiers during a stimulation. Additionally, the method may include shorting, after each stimulation before recording is resumed, inputs of the recording amplifiers to ground to suppress ringing in the recording system.
