Overview
This single-center prospective study aims to investigate the electrophysiological mechanisms of temporal interference (TI) in humans by analyzing clinical, imaging, and electrophysiological data from patients aged 14-60 with drug-resistant epilepsy.
Description
Temporal Interference (TI) technology is a novel non-invasive method for deep brain stimulation (DBS). By generating an overlapping electric field from safe currents, TI creates focused stimulation in targeted deep brain areas. This approach allows for the exploration of deep brain nuclei functions and has the potential to serve as a non-invasive alternative to traditional invasive DBS for clinical treatments.
Stereoelectroencephalography (SEEG) is a method for recording electrical activity from deep brain structures using implanted depth electrodes to provide a three-dimensional view of neuronal activity.
This study aims to investigate the electrophysiological mechanisms of temporal interference (TI) deep brain stimulation by including patients aged 14-60 with implanted intracranial electrodes. During and after TI stimulation, electrophysiological and clinical data will be recorded. Clinical, imaging, and electrophysiological data will be analyzed and processed to advance understanding of TI's effects in deep brain stimulation.
