Textbook in PDF format The dogma that brain function relied on the cortex has dominated clinical neurology, neurosurgery and psychiatry for the last 100 years. Since the start of the 2000s, it has become evident that brain function is orchestrated as a network through white matter connections. This framework provides an understanding of brain function and dysfunction, and has radically changed how neurosurgical resections are performed. There is currently no manual for clinicians to visualize this functional anatomy in a fast, easy and user-friendly way. This is particularly important for senior clinicians who may have an understanding of cortical anatomy but may struggle with newly described white matter connections as they may now be visualized with MRI, and also for trainees who are learning the subject of applied neuro-anatomy. With this book, we aim to bridge this gap
