A canonical visualization tool for SEEG electrodes

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. The code and graphical user interface are available at:https://github.com/MultimodalNeuroimagingLab/mnl_seegview

Automated summary

SEEG electrodes are implanted in patients with refractory epilepsy to locate seizure foci, and are used in neurophysiology research to determine focal brain activity. Clear visualization of SEEG electrode location on MRI scans is crucial for neuroscientific understanding. An open-source software tool has been developed for visualizing SEEG electrode positions in relation to brain anatomy.
