Abstract
Systems and methods are disclosed herein for recording electrical signals in the presence of artifacts. The system and methods can employ multiple techniques for attenuating large, unwanted artifacts while preserving lower amplitude desirable signals. Aspects that can improve the recording of electrical signals in the presence of larger artifacts include particular electrode placement and spacing, high dynamic range amplification with good linearity, and signal blanking. Combinations of more or fewer techniques can be employed to achieve the desired attenuation of signal artifacts while preserving the desired signal. The systems and methods are suitable for recording neural signals in the presence of electrical stimulation signals.
