N. Mavroudakis et al., DISSOCIATION OF P13-P14 FAR-FIELD POTENTIALS - CLINICAL AND MRI CORRELATION, Electroencephalography and clinical neurophysiology, 88(3), 1993, pp. 240-242
P13 and P14 far-field potentials are recorded over the scalp with medi
an nerve stimulation when non-cephalic reference is used to measure so
matosensory evoked potentials. The dissociation of these 2 potentials
is exceptional. Only 2 cases subsequent to pontine lesions have been d
escribed hitherto. We report the case of a 31-year-old woman with a lo
w grade glioma located at the spino-medullary junction who presented a
P13-P14 far-field dissociation. This case fully supports the independ
ent nature of the P13 and P14 potential generators.
