When delivered at low frequencies (0.05 Hz, every 20 s), SPES allows quantitative assessment of dynamic network interactions while avoiding long-term synaptic modifications. These stimulation-induced responses, recorded via stereoelectroencephalography (SEEG), reveal both local and distributed neural activity with millisecond precision.",[13],"Procedure: SEEG recordings and SPES",[15],{"type":16,"name":17,"description":18,"armGroupLabels":19,"otherNames":20},"PROCEDURE","SEEG recordings and SPES","This study will utilize stereoelectroencephalography (SEEG) recordings combined with single-pulse electrical stimulation (SPES) to investigate functional brain connectivity and cortical excitability patterns in patients with epilepsy during both wakefulness and sleep states. The SEEG recordings will provide high-resolution intracranial electrophysiological data, while SPES will be employed to actively probe and quantify cortico-cortical connections. This combined approach will enable characterization of state-dependent neural network dynamics.",[9],null,[22],{"name":23,"affiliation":5,"role":24},"Liankun Ren, MD","PRINCIPAL_INVESTIGATOR",[26],{"name":23,"role":27,"phone":28,"phoneExt":20,"email":29},"CONTACT","13681576621","renlk2022@outlook.com",[31],{"facility":5,"status":32,"city":33,"state":34,"zip":35,"country":36,"cosmosGeoPoint":37,"geoPoint":42,"contacts":43},"RECRUITING","Beijing","Beijing Municipality","100000","China",{"type":38,"coordinates":39},"Point",[40,41],116.39723,39.9075,{"lat":41,"lon":40},[44],{"name":23,"role":27,"phone":45,"phoneExt":20,"email":29},"+86 13681576621",{"type":24,"investigatorFullName":47,"investigatorTitle":48,"investigatorAffiliation":5,"oldNameTitle":20,"oldOrganization":20},"Liankun_Ren","Professor","100556390",false,"NCT06524479","Investigating the Functional Characteristics During Wakefulness and Sleep Based on SEEG","Inclusion Criteria:\n\n* Drug-resistant focal epilepsy\n* Justified SEEG exploration in the context of presurgical assessment of epilepsy\n* Subjects will be a part of the epilepsy-monitoring unit for long-term SEEG recordings and analysis\n* Written non-opposition to study participation\n\nExclusion Criteria:\n\n* Pregnant women (Contraindication to SEEG exploration)\n* Subjects that experience surgical complications during the implant procedure will be excluded from the study","ALL","14 Years","65 Years",{"count":58,"type":59},20,"ESTIMATED","INTERVENTIONAL",[62],"NA","This study aims to collect electrophysiological and clinical data from patients aged 14-65 with drug-resistant epilepsy who underwent SEEG.
