Abstract

The magnetoencephalogram (MEG) may be used to localize and study synchronized cellular currents during physiological and pathological cortical activities in animal and man. However, a detailed interpretation of the magnetic responses requires an understanding of the relationship between the cellular currents and the resultant electric and magnetic fields. Based on the theoretical prediction that MEG fields are induced predominantly by intracellular currents (Cohen and Hosaka, 1976; Barth et al., 1986; Okada, Y. C., 1987), MEG animal studies, combined with electrical measurement, may provide valuable information for understanding the neurogenesis of cortical responses.
