it is our privilege and pleasure to invite you to the 11th World Congress of Biological Psychiatry. The World Federation of Societies of Biological Psychiatry (WFSBP) has chosen Kyoto for our next World Congress in 2013 in the field of biological psychiatry and psychopharmacology. After the big success of the Prague meeting in 2011, Kyoto is the ideal setting to discuss the current advances in biology and molecular genetics, the development of new drugs based upon new mo- lecular concepts, and the advances in modern technologies and neuroscience that will change our concepts and attitudes towards our patients. During this outstanding scientific event, opinion leaders from all around the world will share with us the newest innovations in the field and their impact on diagnoses, treatment and quality of life of our patients. High scientific level sessions will be organized: intensive Workshops and Debates, Plenary Lectures with well known experts in the field and Symposia. Young scientists are especially encouraged to present their recent findings through Free Communications, Posters and Young Scientists Award Sessions, which will be dedicated to them. The general aim of the scientific programme will be the biological and molecular basis of mental diseases which will contribute to improve our patients‘ everyday life. The Japanese Society of Biological Psychiatry (JSBP) is honored to host the 11th World Congress of Biological Psychiatry in Kyoto, the city of culture and tradition. JSBP, founded in 1978, is now fully prepared to organise a congress of high quality with high scientific caliber, comfortable atmosphere, and rich hospitality. About 1,600 members of JSBP have already started the preparation for the 11th World Congress making use of the international and domestic network of the colleagues in this field. Kyoto, the former imperial capital of Japan, is the most attractive location for the 11th World Congress of Biological Psychiatry. We encourage you to submit your abstracts for free communications and posters until 22 January 2013 online on this website.
