More specifically, a combined recording of electroretinography (ERG) and visual-evoked potentials (VEP) can functionally dissect the visual pathway and identify the site of dysfunction in pediatric patients, whether retina, optic nerve, or visual cortex is the primary cause of vision loss.Modern visual electrophysiology systems allow ERGs and VEPs to be recorded simultaneously, which is ...
EMG (electromyography) is the measurement of electrical activity associated with the activation of a muscle group as detected by non-invasive electrodes on the surface of the skin. Spatial mode allows the device to track its location in space and create a switch based on that location. ...
Despite these promising results, challenges remain in the use of sEMG for unobtrusive monitoring of hand motion. sEMG requires the use of bulky electrodes with complex signal acquisition and amplification hardware, and a high signal sampling rate. In addition, given that sEMG is measuring the electrical activity of muscles, its signal-to-noise ratio is sensitive to the ...
