Abstract

The relative position of the P50m and the N100m sources of the auditory evoked magnetic field remains unclear. Magnetoencephalography was performed in 24 normal subjects. Contralateral P50m to left and right ear stimulus wasobserved in 21 and 19 hemispheres, respectively. Ipsilateral P50m to left and right ear stimulus was observed in 17 and 16 hemispheres, respectively. N100m was observed in all subjects for all stimuli. Relative position of the equivalent current dipole of the P50m was 1.0 +/- 7.6 (mean +/- SD) mm posterior, 2.0 +/- 5.8 mm inferior and 1.8 +/- 8.0 mm medial to the N100m dipole position considering all observations. We suggest that the P50m and N100m sources are colocated in an extended area of the cortex. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
