JNP Podcasts: Improving localization and measurements of M-waves using high-density surface electromyography

In this episode, coauthor Ernesto Bedoy discusses their recently published research, "Improving Localization and Measurements of M-Waves Using High-Density Surface Electromyography." The study presents an innovative approach to enhancing the measurement of evoked potentials through high-density surface electromyography (HD-sEMG). By incorporating spatial filters and ultrasound imaging, the research significantly improves the precision and localization of evoked potentials, providing a more accurate method for assessing motor pathway integrity. These advancements hold promise for developing better tools to detect and treat neurological deficits, offering a significant contribution to the field of neurophysiological research.
