立体脑电地形图(SEEG)电极临床上被植入难治性癫痫患者的脑内，以定位癫痫的发病部位。它们越来越多地被用于神经生理学研究，以确定人类大脑对任务或刺激做出反应的局部活动。在磁共振成像(MRI)扫描上清楚地显示SEEG电极相对于患者解剖的位置对于神经科学的理解是至关重要的。要做到这一点，一种直观的方法是沿着规范的轴向、冠状和矢状面，在最近的MRI切片上绘制大脑活动和电极位置的标签。因此，我们在MatLab中开发了一个开源软件工具，用于将根据计算机断层扫描(CT)确定的SEEG电极位置可视化到重新分割的大脑MRI的规范平面上。代码和图形用户界面可在at:https://github.com/MultimodalNeuroimagingLab/mnl_seegview上使用
Stereoencephalographic (SEEG) electrodes are clinically implanted into the brains of patients with refractory epilepsy to locate foci of seizure onset. They are increasingly used in neurophysiology research to determine focal human brain activity in response to tasks or stimuli. Clear visualization of SEEG electrode location with respect to patient anatomy on magnetic resonance image (MRI) scan is vital to neuroscientific understanding. An intuitive way to accomplish this is to plot brain activity and labels at electrode locations on closest MRI slices along the canonical axial, coronal, and sagittal planes. Therefore, we’ve developed an open-source software tool in Matlab for visualizing SEEG electrode positions, determined from computed tomography (CT), onto canonical planes of resliced brain MRI.
