*3.1. Demographics*

Nine patients (6F, mean age 38.8 *±* 11.28) were included in this study after meeting the inclusion criteria. The patient characteristics, including seizure onset zone, are shown in Table 1. Three of the nine patients presented with highly lateralised seizures; the other six had a mixture of highly lateralised and poorly lateralised seizures. All patients were diagnosed with focal epilepsy; two had experienced frequent focal to bilateral tonic-clonic (FBTC) seizures, whilst another three had infrequent FBTC seizures (experienced more than one year prior to the EEG recording).
