An Extraordinary AEP Product

by Greg Ollick, Sr., M.A.

 

"We brought the new Integrity Gen 2 device into environments loaded with electro- magnetic interference which is very hostile to AEP testing, and the Gen 2 system was virtually unaffected....We were able to get clear, clean ABR and ECocGh responses with the patient awake, sitting up and occasionally talking, and we obtained all of this in substantially less time than with any other system."

The Amplitrode

The world's first patented in-situ bio-amplifier

 

The Amplitrode® pre-filters and amplifies electrophysiological responses at the recording site. This patented award-winning technology eliminates many of the problems related to extraneous noise from surrounding electrical, magnetic and radio frequency (RF) field-induced interference, along with electrophysiological artifacts from patients, and motion artifacts from electrode leads. It enables testing in harsh environments, and eliminates the need to adjust gain or worry about signal clipping.

How it Works

This patented technology provides two distinct innovations: filtering of the ABR before amplification, along with amplification of the signal directly at the recording electrode site. Prefiltering and amplifying immediately at the site of data acquisition, dramatically reduces the chance that undesirable noise is introduced into the signal.

 

Prefiltering: By prefiltering the signal, the effects of EOG, ECG, motion artifact, and RF are almost completely eliminated. Gain adjustments are no longer needed, and the risk of signal saturation is reduced.

 

In-situ amplification: By amplifying the signal "in situ" (at the recording site), sources of noise from the recording environment are reduced. By mounting the amplifier directly on the electrode, close to the source of the signal, there are no intervening wires that can pick up electromagnetic noise and other sources of signal contamination in the environment. The result is the recording of a more robust ABR signal.

 

In conventional AEP systems, the of lack in-situ amplification means that amplification occurs after the signal has had to travel from the electrode, along a cable, all the way to a preamplifier. With the cables acting as an antenna, there is a great deal of opportunity for noise to be introduced from sources present in the recording environment. Line noise and additional wires also contribute to contamination of the signal. Therefore, when the signal reaches the preamplifier, it is contaminated with all sorts of noise which is subsequently amplified. The Amplitrode® overcomes these problems.
