Beño Ruiz De La Sierra, Rosa María Arjona Valladares, Antonio Fondevila Estévez, Sabela Fernández Linsenbarth, Ines Díez Revuelta, Álvaro Molina Rodríguez, Vicente 2023 Producción Científica As we speak, corollary discharge mechanisms suppress the auditory conscious perception of the self-generated voice in healthy subjects. This suppression has been associated with the attenuation of the auditory N1 component. To analyse this corollary discharge phenomenon (agency and ownership), we registered the event-related potentials of 42 healthy subjects. The N1 and P2 components were elicited by spoken vowels (talk condition; agency), by played-back vowels recorded with their own voice (listen-self condition; ownership) and by played-back vowels recorded with an external voice (listen-other condition). The N1 amplitude elicited by the talk condition was smaller compared with the listen-self and listen-other conditions. There were no amplitude differences in N1 between listen-self and listen-other conditions. The P2 component did not show differences between conditions. Additionally, a peak latency analysis of N1 and P2 components between the three conditions showed no differences. These findings corroborate previous results showing that the corollary discharge mechanisms dampen sensory responses to self-generated speech (agency experience) and provide new neurophysiological evidence about the similarities in the processing of played-back vowels with our own voice (ownership experience) and with an external voice. application/pdf https://uvadoc.uva.es/handle/10324/61248 eng Wiley 32 Ciencias Médicas Corollary discharge function in healthy controls: Evidence about self‐speech and external speech processing info:eu-repo/semantics/article TEXT UVaDOC.
