This website was created by Dr. William W. Campbell for showing and sharing common clinical signs related to the practice of neurology and related disciplines. It is designed to complement The Neurologic Examination and Clinical Signs in Neurology with an emphasis on photos and videos. The entries include brief didactic material; more in depth discussion is available in the two textbooks. The intention is to create a community of interested physicians and medical students. Others are invited to contribute material. Apply to become a contributor here.
