A novel technology developed by the Zucker Institute for Applied Neurosciences at the Medical University of South Carolina was able to measure the blink response comparably to electromyography in a validation study of ten healthy college students, according to an article published online on Dec. 12, 2017 by the IEEE Journal of Translational Engineering in Health and Medicine. The blink response can be an important indicator of neurological status.
