Functional Systems.

In this chapter, some of the main CNS structures are grouped together with particular respect to their functional activity. The classification is somewhat arbitrary and covers only a practical aspect: to allow easy identification of a possible lesion location based on symptoms and signs. The main systems are considered on the following pages, while other systems are dealt with together with their cranial nerves. Several other complex cerebral functions not routinely visible through neuroradiological studies are not considered in this chapter. [ABSTRACT FROM AUTHOR]
