The goal of this study proposal is to develop a biorepository which will collect and store central nervous system (CNS) tissue or cerebral spinal fluid (CSF) for future research. This material will be collected from children with CNS conditions or defects. This will be a very useful resource to scientists who work to develop new approaches to prevent and treat conditions that affect children's brains and nervous systems.

The purpose of this research study is to study the utility of advanced blood testing for patients who have had a stroke and tend to form blood clots more than usual. The study involves blood tests using a new testing system that may detect issues with blood clotting easier than conventional tests. This is a 12-month study and will involve one blood draw and follow-up phone calls

Hypermobile EDS and hypermobile spectrum disorder (collectively referred to as hEDS) are estimated to affect 1 in 500 individuals worldwide. hEDS patients have limited treatment options for their numerous symptoms that impact the quality of life. This clinical trial tests a new ear stimulation method in hEDS patients to determine if it may improve quality of life.

Currently rTMS for treating depression is delivered without knowing whether the TMS pulses are synchronized with the patient's brain rhythms. We will study healthy and depressed adults with TMS inside of the MRI scanner or outside of the MRI scanner using optics, and test whether it matters precisely timing the TMS pulses with EEG.
