The modern understanding of the pathogenesis of migraine, based on the concept that it is a neurovascular disorder, is often thought to have emerged from the work of Harold Wolff in the period 1932-1962. However, over the preceding 300 years, from William Harvey onwards, various hypotheses of the pathogenesis of migraine had been proposed, a few bearing reasonably strong resemblances to Wolff's ideas, though based on less adequate evidence. Many of these earlier hypotheses regarded migraine either primarily as a vascular (e.g., Willis, Wepfer, Latham) or as a neural disorder (e.g., Harvey, Lieving and his 'nerve storms'). There were also variations around these two major themes and in the 19th Century a number of neurovascufar type hypotheses emerged assigning a major role in migraine pathogenesis to the autonomic nervous system. In addition, during the three centuries there were a number of other hypotheses based on different postulated pathogenic mechanisms, some quite ingenious, which had relatively brief vogues. No hypothesis has yet proved capable of explaining all the features of migraine satisfactorily. (c) 2005 Elsevier Ltd. All rights reserved.

Two nineteenth-century Balinese genres in which the erotic predominates are epic kakawin poetry and tutur (religious manuals) on sexual yoga. The article points to the strong intertextual links between these diverse genres. Through their focus on practical sexual matters and on the pursuit of sexual pleasure as integral to spiritual growth, tutur and kakawin also offer insight into notions of gender and sexuality in nineteenth-century Bali.
