Sources Of Scalp Potentials

The generators of scalp potentials are best described as microcurrent sources at cell membranes. Relationships between such very small-scale sources and macroscopic potentials at the scalp are made easier by employing an intermediate (mesoscopic) descriptive scale. This approach makes use of the columnar structure of neocortex, believed to contain the dominant sources of spontaneous scalp potentials. For macroscopic measurements, the "source strength'' of a volume of tissue is defined by its electric dipole moment per unit volume:
