Simulation of Motor Unit Action Potential Recordings From Intramuscular Multichannel Scanning Electrodes

Motor Unit Action Potential Quantitation

In vitro multichannel single-unit recordings of action potentials from mouse sciatic nerve.

Electrode arrays interfacing with peripheral nerves are essential for neuromodulation devices targeting peripheral organs to relieve symptoms. To modulate (i.e., single-unit recording and stimulating) individual peripheral nerve axons remains a technical challenge. Here, we report an in vitro setup to allow simultaneous single-unit recordings from multiple mouse sciatic nerve axons. The sciatic...

Multichannel thin-film electrode for intramuscular electromyographic recordings.

It is currently not possible to record electromyographic (EMG) signals from many locations concurrently inside the muscle in a single wire electrode system. We developed a thin-film wire electrode system for multichannel intramuscular EMG recordings. The system was fabricated using a micromachining process, with a silicon wafer as production platform for polyimide-based electrodes. In the curre...
