Abstract:
This study was aimed for comparison of efficacy in detecting epileptiform discharges, which was originating from mesiobasal temporal lobe, among the four non-standard non-mvasive skm surface electrodes such as ear lobe(Al/A2), zygomatic(Zl/Z2), surface sphenoidal(SS1/SS2) and true anterior temporal electrode(Tl/T2). The study was performed with simultaneous placement of the nonstandard electrodes including standard electrodes(F7/F8). The resul ts were as follows. Among the non-standard electrodes, zygomatic and true anterior temporal electrodes detected more epileptiform discharges compared to the other two electrodes, although there was no statistical significancy. Compared to the standard electrodes, zygomatic and true anterior temporal electrode showed statistically high significant detecting rate (p<0. 01). Also average detection rate of epileptiform discharges of the whole non-standard electrodes which was compared to the rate of the standard electrodes showed statistically significance (p<0.05). In conclusions, non-standard surface electrodes, especially zygomatic and true anterior temporal electrode, are considered as valuable to detect the epileptiform discharges from temporal lobe if they were used at the routine initial EEG examination.
