Abstract
Artifacts due to delivery of an electrical signal (e.g., for neural stimulation or nerve block) can be eliminated from neural recordings. An activating stimulus (AS) can be applied by at least one neural electrode located at a first position within a body or a preparation proximal to a neural structure. The AS includes an electrical waveform configured to affect (e.g., stimulate or block) conduction in the neural structure. A counter stimulus (CS) can be applied by at least one electrode located at a second position within the body or the preparation remote from the neural structure. The CS includes an electrical waveform configured with a timing parameter and an amplitude parameter selected based on a feature of the AS. Artifacts due to the AS can be blocked by the CS during the neural recordings.
