摘要：
An implantable device for measuring a neural response to a stimulus, the device comprising: a plurality of electrodes that include one or more nominal stimulus electrodes and one or more nominal sense electrodes； a source of stimulus to provide a stimulus to be administered from one or more stimulation electrodes to the neural tissue； measurement circuitry to amplify a neural signal detected in one or more detection electrodes； and a control unit configured to control the application of a stimulus to the neural tissue and the measurement of a provoked neural response, the control unit being further configured to recover the charge on the stimulus electrodes by short-circuiting the stimulation electrodes with each other, being The control unit further configured to cause the stimulus source to apply an electrical stimulus from the stimulus electrodes to the neural tissue while maintaining the or each detection electrode disconnected from the measurement circuitry, the control unit being further configured to impose a delay during which the stimulus electrodes are in the open circuit and the detection electrode is disconnected from the measurement circuitry and the stimulus electrodes, and the control unit being further configured to measure a neural response signal present in the detection electrode connecting the or each detection electrode to the measurement circuitry after the delay； characterized in that the control unit is further configured to adjust the measurement circuitry before a stimulus by connecting the or each detection electrode to the measurement circuitry to allow the measurement circuitry to be set in a bioelectrically defined stable state.Un dispositivo implantable para medir una respuesta neural a un estímulo, comprendiendo el dispositivo: una pluralidad de electrodos que incluyen uno o más electrodos de estímulo nominal y uno o más electrodos de sentido nominal； una fuente de estímulo para proporcionar un estímulo a administrar desde uno o más e
