Claim Text:
1. A method for measuring a neural response to a stimulus, the method comprising: settling measurement circuitry prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state; recovering charge on stimulus electrodes by short circuiting the stimulus electrodes to each other; applying an electrical stimulus from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry; imposing a delay during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes; and after the delay, measuring a neural response signal present at the sense electrode by connecting the sense electrode to the measurement circuitry.
