摘　　要：目的初步探讨健康成人睡眠期枕区一过性正相尖波(POSTS)脑磁图与脑电图的对应关系,并总结脑磁图POSTS波形和分布特点。方法同步采集2020年12月至2021年8月首都医科大学附属北京天坛医院招募的5例健康受试者睡眠期脑磁图与脑电图数据,分析脑磁图POSTS波形特点及其与脑电图POSTS的对应关系,采用单一等效电流偶极子方法对脑磁图POSTS进行溯源分析。结果共5例受试者共记录到睡眠期脑电图POSTS波形564个,剔除与心电图重合的POSTS波形后,同步出现的脑磁图对应枕区POSTS波形359个,脑磁图POSTS检出率为73.42%(359/489)。脑磁图POSTS波形变异性较大,POSTS偶极子主要分布于双侧枕叶中线区,包括距状沟、舌回、楔叶等,部分分布于距中线较远的枕颞内侧回、枕颞外侧回、枕皮质外侧等,少数分布于顶枕沟和楔前叶。结论脑磁图POSTS具有不同于脑电图POSTS的特点,临床判读时应注意识别,以更好地辨别生理性与病理性波形,为术前评估提供准确参考。ObjectiveTo preliminarily explore the correlation of positive occipital sharp transientsof sleep(POSTS) in MEG and EEG,and summarize the characteristics of MEG POSTS morphology andlocalization.MethodsThe MEG and EEG signals were simultaneously recorded in 5 healthy subjectsduring sleep,who were recruited from December 2020 to August 2021 in Beijing Tiantan Hospital,CapitalMedical University.The features of MEG POSTS and its relationship with EEG POSTS were summarized.Single equivalent current dipole(ECD) model was used to conduct source imaging for POSTS.Results About 564 EEG POSTS during sleep were recorded in 5 subjects.There were 359 simultaneous MEGPOSTS in occipital region after exclusion of the POSTS overlapping with heart beat in ECG.Theappearance rate of MEG POSTS was 73.42%(359/489).The MEG POSTS showed great variability inmorphology.MEG POSTS dipoles were located mainly in bilateral midline regions of occipital lobe,including calcarine sulcus,lingual gyrus and cuneus;some in other parts of occipital lobe away frommidline regions,such as medial occipitotemporal gyrus,lateral occipitotemporal gyrus and lateral occipitalcortices;and a small portion in bilateral parietooccipital sulcus and precuneus.ConclusionsMEG POSTShas characteristics different from EEG POSTS,so it is important to recognize POSTS correctly in clinicalMEG reading to discriminate between physiological and pathological waves and provide precise informationfor presurgical evaluation of epilepsy.
