Abstract

Hearing one´s own name plays an important roll in external communications and internal cognition within our minds. Though hearing one´s own name well has been studied, the relationship between hearing one´s own name and self-awareness is not understood. In this study, we focused on brain responses to hearing one´s own name. In order to assess the pattern of ERP and the power of EEG frequency during hearing one´s own name, we used a passive oddball paradigm that included the subject´s own name (SON). The grand average ERP showed that mismatch negativity and novelty p300 were elicited by SON. Time frequency analysis revealed that theta power and beta power were increased around 400-600 ms after stimulus by SON.
