A method for processing a neural measurement obtained in the presence of artifact, in order to detect whether a neural response is present in the neural measurement. A neural measurement is obtained from one or more sense electrodes. The neural measurement is correlated against a filter template, the filter template comprising at least three half cycles of an alternating waveform, amplitude modulated by a window. From an output of the correlating, it is determined whether a neural response is present in the neural measurement.

Provided herein is a system comprising (1) a microelectrode array (MEA) component comprising an integrated multiplexed (MUX) logic circuit; and (2) a microprocessor, e.g., MOSFET, such as a CMOS, wherein the MEA is in electrical communication with the microprocessor such that signals produced by the microelectrodes are transmitted to the processor through the MUX. The use of a MUX reduces the number of outputs used to communicate signals from multiple microelectrodes to the microprocessor. The two components are removably engageable with each other such that after one or more uses, the engaged MEA can be removed and replaced with a new MEA, without the necessity of disposing the microprocessor.

A method for measuring a neural response to a stimulus. Measurement circuitry is settled 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. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.
