Spike voltage topography identifies two types of frontotemporal epileptic foci.

摘要: We characterized voltage topography of frontotemporal EEG spikes in 24 patients with complex partial seizures and identified two distinct patterns. "Type 1" possessed a "dipolar" field negative region over the inferolateral temporal scalp positive contralateral, centroparietal scalp. 2" showed only broad, field. One or other spike type predominated all but patients. Correlations clinical data intracranial suggest that 2 arise from frontal neocortex, while 1 involve mesial structures as well lateral cortex.
