The primary objective of recording EEG signal at a particular location on the scalp is to know the electrical activity of the brain right below the electrode position. However, signals of cerebral origin from areas beneath adjacent electrodes also gets superimposed on the original signal of interest. In this paper, we are proposing a least squares technique for estimating the effect of adjacent activities and subsequently subtracting it from the recorded EEG so as to get a better estimate of the activity beneath the electrode of interest. The results show that the processed signal better reflects the activities below the electrode location than the one originally recorded.
