1. A method for measuring a neural response to an electrical stimulus, the method comprising:
applying the electrical stimulus from stimulus electrodes to neural tissue, while keeping a sense electrode disconnected from measurement circuitry;
imposing, after applying the electrical stimulus, a post-stimulus delay during which the sense electrode is kept disconnected from the measurement circuitry; and
amplifying, after the post-stimulus delay, a neural response signal present at the sense electrode by connecting the sense electrode to the measurement circuitry.
