Summary

This prospective exploratory interventional study aims to investigate the neurophysiological effects and safety of multi-parameter temporal interference (TI) stimulation in patients undergoing stereoelectroencephalography (SEEG) monitoring. Participants who have already undergone SEEG electrode implantation for clinical indications will receive non-invasive TI stimulation targeting selected deep brain regions according to their individual electrode coverage and neuroimaging data. Multiple stimulation frequencies will be tested while intracranial SEEG signals are recorded before, during, and after stimulation. The study will characterize frequency-dependent changes in local and distributed brain activity and explore the relationship between TI stimulation parameters and neurophysiological responses, providing in vivo evidence for parameter optimization of non-invasive deep brain stimulation.

Conditions

Interventions

DEVICE

Temporal Interference Stimulation

Participants will receive individualized temporal interference (TI) stimulation targeting one or two deep brain regions selected according to SEEG electrode coverage and individual neuroimaging data. Scalp electrode placement and stimulation intensity will be optimized using individualized finite-element modeling. Multiple beat-frequency conditions corresponding to delta, theta, alpha, beta, gamma, and high-gamma frequency ranges will be administered in randomized order. SEEG activity will be recorded before, during, and after stimulation.
