Root Clustering in Parameter Spacen accumulated. Before considering these data and entering into a discussion of the current ideas concerning the origin of the EEG, it is essential that we look at the neurons — the cellular units of the nervous system. We will examine them from the points of view of anatomical structure and generation of bioelectric activity.

At the same time, the person reading and interpreting the records will find it necessary to deal with concepts and techniques that are markedly different from those encountered in EEG interpretation.

Root Clustering in Parameter Spaceand what actually takes place when you attach a pair of electrodes to a person’s scalp and connect the other ends of the wires to a channel of the EEG machine, it is necessary to consider some of the basic theory involved.

The magnitude of the complexity already was recognized in 1853 by Hermann Helmholtz who noted that a given “electromotive surface” may reflect an infinite variety of internal electrical fields (Helmholtz H, 1853).
