A brief history of cortical functional localization and its relevance to neurosurgery

Abstract

Modern cortical mapping is a cornerstone for safe supratentorial glioma resection in eloquent brain and allows maximal resection with improved functional outcomes. The unlocking of brain functionality through close observation and eventually via cortical stimulation has a fascinating history and was made possible by contributions from early physician-philosophers and neurosurgery's founding fathers. Without an understanding of brain function and functional localization, none of today's modern cortical mapping would be possible.
