Zusammenfassung:A system and method detect neuronal action potential signals from tissue responding to electrical stimulation signals. A compound discharge latency distribution (CDLD) of the neural tissue is derived by deconvolving a tissue response measurement signal taken responsive to electrical stimulation of the neural tissue by a stimulation electrode, with an elementary unit response signal representing voltage change at a measurement electrode due to the electrical stimulation. The CDLD is compared to known physiological data to detect an NAP signal from the tissue response measurement signal.
