Abstract

System and methods that cancel artifacts of stimulation signals from neural signals are disclosed. In several embodiments, the systems and methods determine a threshold value for the neural signal in the absence of artifacts. The threshold value can then be used to detect an artifact in received neural signals. In a number of embodiments, a template can be used to cancel an artifact from a neural signal in response to the neural signal being greater than the threshold value.
