The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database 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. Individual papers published in influential multidisciplinary journals such as Nature and Science are also assigned to their appropriate fields. Both articles tabulated and citation counts to those articles are for the period indicated.
Here journals in neuroscience and behaviour are ranked by citations per paper to reveal weighted impact. Essential Science Indicators lists journals ranked in the top 50 percent for a field over a given period, based on total citations. In neurosciences and behaviour, 143 journals are listed, meaning 286 journals in this field were surveyed. Of these 143 journals, 130 published 500 or more papers during the period. This ranking should be recognized as distinct from the Thomson Reuters impact factor rankings, which are presented in the Journal of Citation Reports issued each year. The impact factor is calculated as citations in Year 3 to a journal’s contents in Years 1 and 2, divided by the number of so-called citable items (regular articles and reviews). Thus, the ranking reveals longer-term impact (citations per paper).
