Characterizing SEPs from Pacinian-targeted vibrations

Year: 2025

Type: article

Abstract: Somatosensory-evoked potentials (SEPs) are commonly studied using transcutaneous nerve stimulation, which does not reflect the selective engagement of mechanoreceptors in natural touch. Here, we use naturalistic vibrotactile stimuli to selectively target Pacinian mechanoreceptors. We quantify the scaling of short- and long-latency SEPs with vibration amplitude and uncover key differences from electrically evoked responses. This work enhances the ecological validity of SEP research and provides a framework for studying neural responses to real-world touch.
