Investigating the Functional Characteristics During Wakefulness and Sleep Based on SEEG

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.
