Abstract
Disclosed herein are of systems, methods, and computer-program products for removing stimulation artifacts of electrical physiological recordings that contain both the stimulation artifact and the neural response.
Claims45
A method of removing stimulation artifacts from physiological recordings to determine a neural response comprising:
- receive a recorded waveform trace, wherein the recorded waveform trace includes a stimulation artifact and a neural response, said recorded waveform trace recorded for a first period of time;
- model the stimulation artifact of the recorded waveform trace as a rational function by fitting the rational function to the recorded waveform trace;
- and
- subtract the fit rational function from the recorded waveform trace to arrive at the neural response.

A system for removing stimulation artifacts from physiological recordings to determine a neural response (eCAP) comprising:
- a memory;
- and
- a processor in communication with the memory, wherein the processor executes computer-executable instructions stored in the memory, said instructions causing the processor to:
- receive a recorded waveform trace, wherein the recorded waveform trace includes a stimulation artifact and a neural response, said recorded waveform trace recorded for a first period of time;
- model the stimulation artifact of the recorded waveform trace by fitting the rational function to the recorded waveform trace;
- and
- subtract the modeled and fit rational function from the recorded waveform trace to arrive at the neural response (eCAP).
