We compared the ability of subdural and depth electrodes to detect and localize interictal epileptiform discharges (IEDs) in the temporal lobe. Sixteen patients had simultaneous intraoperative recordings with depth and subdural electrodes while undergoing anterior temporal lobe resections under local anesthesia for medically intractable seizures. IEDs that were focal (detected at just 1 or 2 electrode contacts) typically registered at the nearest contact, regardless of type. IEDs that were regional (engaging more than 2 electrode contacts) typically appeared simultaneously at both electrode types. Neither method was better able to indicate whether an IED was mesial or lateral, posterior or anterior. Subdural and depth electrodes seem to provide complementary information on the location of IEDs within the temporal lobe.
我们比较了硬膜下电极和深部电极检测和定位颞叶发作间期癫痫样放电（IEDs）的能力。16例患者在局部麻醉下接受前颞叶切除术以治疗药物难治性癫痫时，同时使用深部电极和硬膜下电极进行术中记录。局灶性IEDs（仅在1或2个电极触点检测到）通常在最近的触点记录，与电极类型无关。区域性IEDs（涉及超过2个电极触点）通常在两种电极类型上同时出现。两种方法都不能更好地表明IEDs是在内侧还是外侧、后部还是前部。硬膜下电极和深部电极似乎在颞叶内IEDs的位置上提供了互补信息。
