Study on Brainwave Responses from Ears: the Event-related Synchronization under the Auditory Stimulus

Huiran Zhang, Yantao Li, Zheng Tang


The event-related synchronization (ERS) is one of the most important functions of brain activities (G. Pfurtscheller, et al. 1992). In order to observe the brain activity of the subjects heard the 40 Hz acoustic stimuli, the event-related potential (ERP) and electroencephalogram (EEG) images of the brain are used to analyze the auditory cortex area. In the present work, observation and exploring study on the brain activities under 40 Hz acoustic stimulus were systemically done by experimental and spectrum analysis technology. And several modes of data visualization are also used. All the data in this experiment suggest that the results of auditory simultaneous stimuli for both ears are present and the brainwave frequency synchronization in the phase with the stimuli is further proved.
