Measurement of dimensionality was applied to the characterization of EEG (electroencephalograph) reference electrodes in common average reference recording. Analysis of simulated average reference EEG was carried out. We applied results of estimated dimension to quantification and characterization of the degree of 'neutralism' (or 'inactiveness') of the common reference electrode. In addition, we investigated effects of number of electrodes and arrangement of electrode array on estimated dimension of average reference potentials, in order to correlate degree of neutralism with EEG recording array. This research study is based on the assumption of 'randomness' of an average reference potential and high-dimensional characteristics of random process.
