Investigating the Functional Characteristics During Wakefulness and Sleep Based on SEEG

NCT06524479 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

No results posted yet for this study

Summary

This study aims to collect electrophysiological and clinical data from patients aged 14-65 with drug-resistant epilepsy who underwent SEEG. The collected data will be analyzed to investigate the functional connectivity during wakefulness and sleep states.

Conditions

  • Refractory Epilepsy
  • Sleep

Interventions

PROCEDURE

SEEG recordings and SPES

This study will utilize stereoelectroencephalography (SEEG) recordings combined with single-pulse electrical stimulation (SPES) to investigate functional brain connectivity and cortical excitability patterns in patients with epilepsy during both wakefulness and sleep states. The SEEG recordings will provide high-resolution intracranial electrophysiological data, while SPES will be employed to actively probe and quantify cortico-cortical connections. This combined approach will enable characterization of state-dependent neural network dynamics.
