The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This data­base, currently covering the period January 1998 through October 2008, 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 Thomson Reuters’ journal-to-category field-definition scheme.

Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations than those publishing fewer papers. This ranking is by citations per paper (impact), among those institutions that have collected 25,000 or more citations in neuroscience and behaviour. For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 437 institutions are listed in the field of neuroscience and behaviour, meaning that a total of 43,700 institutions were reviewed to obtain these results. Of the 437, 81 institutions collected 25,000 or more citations. The ranking by citations per paper (impact) seeks to reveal heavy-hitters based on per-paper influence.
