*Henz Diana, Ultrasound stimulation of the skin stimulates EEG theta activity in speechrelated brain areas, psychophysiology, (September 2019), volume 56 - S1, Poster 2- 072<br>''Several studies have shown distinct effects of ultrasound stimulation on brain activity and cognitive functions. In the present study, we tested whether shortterm application of a language course applied by ultrasound on the skin stimulates specifically brain areas that are related to auditory and speech processing. A language course (German for beginners) was transmitted soundlessly by an ultrasound device with two electrodes placed on the right wrist of the participants. High- density EEG was recorded from 128 electrodes before, during, and after the ultrasound application. Each experimental condition (ultrasound stimulation, no stimulation) was tested for 30 minutes. Data of source localization show increased overall theta activity in the superior temporal gyrus and Wernicke ' s area, as well as the temporo- parietal junction after 15 minutes of ultrasound application. Results indicate that language infomation can be stimulated in the brain by ultrasound application on the skin. Further, activation of the temporoparietal junction indicates that sensory information of the ultrasound stimulation applied on the skin enhances multisensory integration of language information. We discuss the underlying neurophysiological processes and potential application fields of ultrasound stimulation on the skin on language processing and language learning.''
