The database in NeuroGuide is referred to as a “Lifespan” reference normative database because it contains individual subjects that were tested, evaluated and deemed normal that ranges in age from 2 months of age to 82 years of age.  The publications that describe the NeuroGuide lifespan database are listed below:
