Abstract

Electrodermal activity (EDA) may identify the lateralization of a seizure focus based on interictal recordings (Poh et al., Epilepsia, 2009, 50(Suppl. 11):11). Little is known about the laterality of EDA ‘sleep storms’, which consist of sympathetic surges of EDA predominantly during NREM stage 2 and slow wave sleep (Sano and Picard, Conf Proc IEEE Eng Med Biol Soc. 2011;2011:777-80) and whether lateralization may also be present and related to the side of seizure onset.
