Studies of auditory evoked magnetic and electric responses: Modality specificity and modelling

The sources of auditory evoked electric and magnetic responses were modelled with multiple current dipoles. The activity at the auditory cortices, 2.6 cm beneath the skull, explains the observed\(\overline {N100m}\) field distribution. An additional current source near the vertex is needed to explain the corresponding potential distributions. The locations of the current sources of\(\overline {N100m}\) did not show any systematic dependence on the tonal frequency.
