Abstract: Aspects presented herein are directed to techniques for eliminating acquisition related artifacts in electro-physiological recording. In order to eliminate artifacts in neural response recordings, a pair of recordings is made with, respectively, inverted and non-inverted polarity at one pair of electrodes. An the average of the two recordings will eliminate the acquisition artifact without the need for an extra recording, such as a baseline.

Abstract: A method of evaluating a neural response, comprising applying electrical stimulation to a recipient, obtaining from read electrodes read data resulting from the applied stimulation, obtaining an artefact model based at least in part on the read data, and obtaining neural response data by comparing the read data to the artefact model.

Abstract: An alternating recording electrode to eliminate acquisition related artifacts in electro-physiological recording. In order to eliminate artifacts in neural response recordings, a pair of recordings is made with, respectively, inverted and non-inverted polarity at one pair of electrodes. One component of the recording artifact is introduced by the electronics of the acquisition system itself. This is mainly the switch on or acquisitional artifact. Rather than eliminate this by subtracting the result of a recording without stimulus from the actual recording, two recordings based on an alternation of the polarities of the active and reference electrode are used. This alternates the polarity of the external signal but not the internal electrical artifact. Hence the average of the two recordings will eliminate the acquisition artifact without the need for an extra recording of, say, a baseline.
