To test the effectiveness and safety of the drug ravulizumab in patients aged 6-18 years.

The purpose of this study is to test the safety and effectiveness of DNL343.

The purpose of this study is to test the safety and effectiveness of ABBV-CLS-7262 on ALS disease progression.

The purpose of this study is to see how effective intravenous ganaxolone is at decreasing seizures in patients with status epilepticus when other antiseizure medications have not worked.

The purpose of this study is to see if the study drug Onabotulinumtoxin A (BOTOX®), is safe and helps to reduce upper limb essential tremor in adults (18 to 80 years of age) who experienced persistent, bilateral tremor during movement , involving hands and forearms.

We are using specialized functional MRI for people receiving deep brain stimulation surgery to help predict who will benefit most from this procedure.

The purpose of this project is to create and distribute a survey with the intent to collect data about the amount and quality of training critical care physicians receive regarding brain death (i.e., death by neurologic criteria). We are doing because teaching physicians about brain death is not standardized and the subject is complex.

The purpose of this study is to create a biorepository of blood samples form patients with myasthenia gravis that may be used with collaborators in the development of new therapeutics for myasthenia gravis (MG).

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).

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.
