Grenoble-Alpes, 4Department of Psychology, McGill University, 5School of Communication Science and Disorders, McGill University This paper introduces a method for obtaining somatosensory event-related potentials following orofacial skin stretch stimulation. The current method can be used to evaluate the contribution of somatosensory afferents to both speech production and speech perception.
