Margot: When you begin, only enter through the .....ninds/ part. Once you are connected to the site select (1) Neurosciences at NINDS, (2) Clinical Neuroscience Program, (3) Clinical Neuroscience Branch and finally (4) CNB Clinical Studies. It is sort of the "back-door" approach -- I am sure there is a simpler way. But, hey, it works! Good Luck.

How do I get permission?
