Abstract
Extraneural
electrodes are the only class of peripheral nerve interface to be implanted in
humans to correct functional deficits due to neurological impairments.
Chronically implanted cuff electrodes correct foot drop in stroke patients, restore
bladder, bowel, and sexual function in paralyzed patients. This available
technology encourages further understanding of the relationship between action
potential, channel configuration, and the signals– from neural activity in
peripheral nerves– recorded by the electrodes, using mathematical models.
However, the traditional cuff electrode technology falls short when considering
the fact that action potential travels bi-directionally. FIU researchers
have modelled the relationship and designed an improvement to the traditional
nerve signal recording device, by changing the positions of the recording
electrodes along a channel formed on a nerve. This allows the electrode to
discriminate between action potential traveling in opposite directions.
Benefit
· Maximizes the recording signal for action potentials traveling in opposite directions · Capable of distinguishing between opposing action potentials · More accurately records neural signals from peripheral nerves
Market Application
The devices, systems and methods are useful in recording neural activity, and motor activity, for clinical applications, as well as drastically improving the function of neural interface systems.
