“…EEG and MEG source localization techniques are used to localize the generators of epileptic discharges, but the main challenge lies not only in localizing the generators but also in accurately recovering their spatial extension. Therefore, several methods have been designed for localizing spatially extended generators (Chang, Nummenmaa, Hsieh, & Lin, ; Cheyne et al, ; Chowdhury, Lina, Kobayashi, & Grova, ; Chowdhury et al, ; Grova et al, ; Huiskamp, Agirre‐Arrizubieta, & Leijten, ; Jung et al, ; Sohrabpour, Lu, Worrell, & He, ; Zhu, Zhang, Dickens, King, & Ding, ), and source localization with the coherent maximum entropy on the mean (cMEM) method is one such method that has been extensively studied on simulated and clinical data, and provided reliable and accurate localization of the sources of EEG and MEG discharges together with their spatial extent (Chowdhury et al, ; Grova et al, ; Heers et al, ; Pellegrino et al, ). In fact, recently we have compared cMEM with the standard dipole fitting approach on a large cohort of epilepsy patients and showed the reliability of cMEM on MEG source localization of clinical data (Pellegrino et al, ).…”
