The data above were extracted from Thomson Scientific’s Essential Science Indicators database. This database, currently covering the period January 1998 to February 2008, surveys only journal articles (original research reports and review articles) indexed by Thomson Scientific. Articles are assigned to a category based on the journals in which they were published and Thomson Scientific’s journal-to-category field definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. Here our ranking in neuroscience and behaviour is by citations per paper – among nations that collected 10,000 or more citations – to reveal weighted impact. For articles with multiple authors from different nations, each nation receives full, not fractional, citation credit. Essential Science Indicators

lists nations ranked in the top 50 per cent for a field over a given period, based on total citations. In neurosciences and behaviour, 80 nations are listed, meaning that 160 were surveyed. Thirty-three nations earned at least 10,000 citations. Notable are several nations whose relatively small output nonetheless earned them a high per-paper impact: Norway, Wales, Ireland and Hungary.
