Top nations in neuroscience and behaviour

The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This data­base, currently covering the period January 2000 through June 2010, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Both the articles tabulated and citation counts to those articles are for the period indicated.

Here, the ranking in neuroscience and behaviour is by citations per paper among nations with 20,000 or more citations during the period to reveal weighted impact. For articles with multiple authors from different nations, each nation receives full, not fractional, 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 neuroscience and behaviour, 83 nations are listed, meaning 166 were surveyed. Twenty-eight nations collected at least 20,000 citations to their papers during the period. The world average in citation impact

for neuroscience and behaviour was 18.75. Thus, all nations listed to 15th place performed at or above the world average.

Also noteworthy is the performance of England, Scotland and Wales in positions one, four and 13, revealing the UK’s strong performance in the field.
