The purpose of this study is to identify and genomically-characterize individuals with genetically unexplained neurodevelopmental disorders, such as epilepsy. The overarching goal is to provide patients with improved information about the underlying genetic basis of their disorder and illuminate novel genetically-defined treatment approaches in the future.

The purpose of the study is to identify certain processes following brain injury that may be associated with the risk of developing epilepsy.

In this research study we want to learn more about resting state brain networks in patients with Tuberous Sclerosis Complex (TSC). Specifically, we want to know how resting state brain networks can guide surgical planning and improve seizure outcomes.

we want to learn more about seizure activity while a patient with epilepsy is not seizing or is at "rest" using data from resting state intracranial EEG (rs-iEEG) and resting state functional MRI (rs-fMRI).
