The distribution of sensory nerves to the dura matter and cerebral vessels.

For almost a century it has been a well established anatomical fact that the cerebral dura mater and the larger cerebral blood vessels have an abundant nerve supply. Starting with the classical researches of Claude Bernard in the middle of the nineteenth century, scientific interest has been devoted chiefly to the investigation of the functions of the cranial vasomotor nerves, and this interest has continued to the present day in the studies of Cobb, Forbes, and their associates on the vasomotor control of cerebral circulation in health and disease. However, it is only very recently that the afferent nerves supplying intracranial structures have been studied intensively, and serious attempts made to correlate the anatomy of afferent nerves with clinical problems of head pain.
