Abstract
A method for acquiring a physiological response from a test subject, particularly an auditory brainstem response, by presenting a plurality of stimuli, such as a Maximum Length Sequence, detecting electrophysiological signals in response to the stimuli, generating a recover signal based on the stimuli and determining the physiological response from the electrophysiological signals and the recovery signal.

A method for acquiring a physiological response, the method being performed by an automated auditory brainstem response (A-ABR) hardware apparatus and comprising the steps of:
- presenting to a test subject, by the A-ABR hardware apparatus, a plurality of stimuli with variable inter-stimulus intervals;
- detecting, by the A-ABR hardware apparatus, an electrophysiological signal from the test subject in response to the stimuli;
- generating, by the A-ABR hardware apparatus, a recovery signal based on the stimuli, where an amplitude and latency of the recovery signal are modified according to the inter-stimulus intervals of the stimuli;
- and
- determining, by the A-ABR hardware apparatus, a physiological response signal using both the electrophysiological signal and the recovery signal.
An apparatus for acquiring a physiological response, the apparatus comprising:
- a sound transducer that receives a plurality of stimuli with variable inter-stimulus intervals and is configured to present the stimuli to a test subject;
- electrodes that detect an electrophysiological signal from the test subject in response to the stimuli;
- wherein the apparatus is configured to:
- generate a recovery signal based on the stimuli, where an amplitude and latency of the recovery signal are modified according to the inter-stimulus intervals of the stimuli;
- and
- determine a physiological response signal using both the electrophysiological signal and the recovery signal.
