However, eye movement may disturb periorbital electrode recording. To overcome this, we developed mandibular (MA) and chin (CH) electrodes and examined whether these electrodes could detect hippocampal epileptiform discharges.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Methods: <\/jats:title>\n<jats:p>This study included a patient with MTLE, who underwent insertion of bilateral hippocampal depth electrodes and video-electroencephalographic (EEG) monitoring with simultaneous recordings of extra- and intracranial EEG as part of a presurgical evaluation. We examined 100 consecutive interictal epileptiform discharges (IEDs) recorded from the hippocampus and two ictal discharges. We compared these IEDs from intracranial electrodes with those from extracranial electrodes such as MA and CH electrodes in addition to F7\/8 and A1\/2 of international EEG 10-20 system, T1\/2 of Silverman, and periorbital electrodes. We analyzed the number, rate of laterality concordance, and mean amplitude of IEDs detected in extracranial EEG monitoring and characteristics of IEDs on the MA and CH electrodes.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results: <\/jats:title>\n<jats:p>The MA and CH electrodes had nearly the same detection rate of hippocampal IEDs from other extracranial electrodes without contamination by eye movement. Three IEDs, not detected by A1\/2 and T1\/2, could be detected using the MA and CH electrodes. In two ictal events, the MA and CH electrodes detected the ictal discharges from the hippocampal onset as well as other extracranial electrodes.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>The MA and CH electrodes could detect hippocampal epileptiform discharges as well as A1\/A2, T1\/T2, and peri-orbital electrodes. These electrodes could serve as supplementary recording tools for detecting epileptiform discharges in MTLE.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_1164_2022","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T07:16:55Z","timestamp":1685690215000},"page":"189","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Mandibular and chin electrodes as a supplemental recording for detection of epileptiform discharges in mesial temporal lobe epilepsy"],"prefix":"10.25259","volume":"14","author":[{"given":"Takafumi","family":"Shimogawa","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayumi","family":"Sakata","sequence":"additional","affiliation":[{"name":"Department of Clinical Chemistry and Laboratory Medicine, Kyushu University Hospital, Fukuoka, Japan."},{"name":"Department of Health Sciences, Division of Medical Technology, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eriko","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Clinical Chemistry and Laboratory Medicine, Kyushu University Hospital, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobutaka","family":"Mukae","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Shigeto","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Division of Medical Technology, Fukuoka, Japan."},{"name":"Department of Neurology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiko","family":"Mukaino","sequence":"additional","affiliation":[{"name":"Department of Neurology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiki","family":"Okadome","sequence":"additional","affiliation":[{"name":"Department of Neurology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Department of Neurology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Yoshimoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takato","family":"Morioka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hachisuga Hospital, Fukuoka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2023,6,2]]},"reference":[{"key":"10.25259\/SNI_1164_2022\/ref-1","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1097\/WNP.0000000000000814","article-title":"Tongue as a wire?
