NCT06663969

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Electrophysiological changes

    Electrophysiological waveform changes recorded by stereoelectroencephalography (SEEG) before, during, and after TI stimulation.

    During the trial(up to 3 hours for each subject)

Secondary Outcomes (1)

  • Patient's subjective feelings and symptoms

    During the trial(up to 3 hours for each subject)

Study Arms (1)

Temporal Interference

EXPERIMENTAL

The investigators performed temporal interference (TI) stimulation to patients with drug-resistant epilepsy undergoing SEEG monitoring. They observed electrophysiological activity and clinical manifestations before, during, and after stimulation to investigate the electrophysiological mechanisms of TI.

Other: Temporal Interference

Interventions

Researchers applied temporal interference (TI) stimulation to the deep brain nuclei of patients who had undergone SEEG monitoring, recording changes in electrical activity detected by SEEG.
