Dynamic changes of interictal post-spike slow waves toward seizure onset in focal cortical dysplasia type II

Highlights • Power of post-spike slow wave increased in all areas from interictal to preictal period. • Power of post-spike slow wave within the seizure onset zone (SOZ) was significantly higher than that outside SOZ during preictal period. • Post-spike slow wave with high power became confined to S...

Summary:Highlights • Power of post-spike slow wave increased in all areas from interictal to preictal period. • Power of post-spike slow wave within the seizure onset zone (SOZ) was significantly higher than that outside SOZ during preictal period. • Post-spike slow wave with high power became confined to SOZ toward seizure onset.
