title: Neuroanatomy of the oculomotor system. The nucleus prepositus.
abstract: The heterogeneous cytoarchitecture of nucleus prepositus hypoglossi and its multiplicity of afferent and efferent connections to oculomotor structures are described. They are more than adequate to account for a role in eye and head movements: it is suggested that they may provide the neuroanatomical basis for an efference copy signal of eye position, which would also be important in gaze-holding.
