Abstract
To represent the overall potential distribution on the entire scalp it is necessary to interpolate between sampled EEG(electroencephalogram) values, we describe a method to interpolate between scalp recorded EEG data which obtained from electrodes irregularly disposed on the scalp, using polynomial interpolation. This method can analyze the variance of source temporally or spatially and present continuous distributed topographic mapping of the EEG records. In the result, we obtained the overall potentials distribution on the entire scalp from the EEG records of a patient which was known to epilepsy.
