Recorded data derives the power spectra maps of EEG with different references. From left to right, the references are left ear (LE), LM, AR and REST. Compared to REST, the power spectra maps show shifts to the right, frontal and superficial positions with LE, to frontal and superficial positions with LM, and to a deeper position with AR. (The Alpha 1 and Alpha 2 maps were reported in Yao et al. 2005)
