It is a great privilege for us to have the opportunity to contribute to this book in honour of Torleiv Høien’s 60th birthday. His views on dyslexia and learning disabilities have greatly influenced our own thinking over the years, and has had a profound influence on the Norwegian scene. Together with his colleagues in Norway and the Nordic countries, Torleiv Høien has set the standards for both research and clinical practice with regard to dyslexia and learning disabilities over the last decades. It is especially intriguing to us that Torleiv Høien and his colleagues were among the first to show a relationship between brain structure and phonological processing in the now classic paper on absence of planum temporale asymmetry in dyslexic children (Larsen, Høien, Lundberg, & Ødegaard, 1990). This is probably one of the most cited papers during the last decade on biological markers of dyslexia.
