Abstract
A method for measuring an electrophysiologic response of a sensory system includes stimulating the sensory system with a first stimulus train having stimuli temporally separated from each other by a first inter-stimulus interval and simultaneously stimulating the sensory system with a second stimulus train having stimuli temporally separated from each other by a second inter-stimulus interval different from the first inter-stimulus interval. A response signal is then sampled at a first frequency corresponding to the first inter-stimulus interval, thereby obtaining a first response train. The first response train is then processed to suppress a contaminant caused by the second stimulus train.

A method for measuring an electrophysiologic response of a sensory system, said method comprising:
- stimulating said sensory system with a first stimulus train having stimuli temporally separated from each other by a first inter-stimulus interval;
- simultaneously stimulating said sensory system with a second stimulus train having stimuli temporally separated from each other by a second inter-stimulus interval different from said first inter-stimulus interval;
- sampling a response signal at a first frequency corresponding to said first inter-stimulus interval, thereby obtaining a first response train;
- and
- processing said first response train to suppress a contaminant caused by said second stimulus train.
A data acquisition-system for measuring an electrophysiologic response of a sensory system, said system comprising:
- a first stimulator for stimulating said sensory system with a first stimulus train having stimuli temporally separated from each other by a first inter-stimulus interval;
- a second stimulator for simultaneously stimulating said sensory system with a second stimulus train having stimuli temporally separated from each other by a second inter-stimulus interval different from said first inter-stimulus interval;
- a first sampler for sampling a response signal at a first frequency corresponding to said first inter-stimulus interval, thereby obtaining a first response train;
- and
- a processor configured for processing said first response train to suppress a contaminant caused by said second stimulus train.
A computer-readable medium having encoded thereon software for measuring an electrophysiologic response of a sensory system, said software comprising instructions for:
- stimulating said sensory system with a first stimulus train having stimuli temporally separated from each other by a first inter-stimulus interval;
- simultaneously stimulating said sensory system with a second stimulus train having stimuli temporally separated from each other by a second inter-stimulus interval different from said first inter-stimulus interval;
- sampling a response signal at a first frequency corresponding to said first inter-stimulus interval, thereby obtaining a first response train;
- and
- processing said first response train to suppress a contaminant caused by said second stimulus train.
