According to Ulrich's International Periodicals Directory (1997), the number of newly-established journals in the field of neurological science has been tending to increase and 92 new journals were established in 1980's, the greatest number ever. In Japan, there was a correlation between the value of the impact factor and numbers of newly established holding journals. Brain Research, Neurology, and Journal of Comparative Neurology were selected as the core journals in the field of neurological science in the 1984 and 1995 edition of the two-step model targetting 85 journals in the neurological science field. The impact factor of the Journal of Neuroscience suddenly began to increase in 1988, and it was the journal with greatest increase in value in the field of neurological science. The field of neurological science, from the stand point of linkage with the physiological science field, has deepened its links with the core journals of the natural science field. This reflects the fact that the field of neurological science is rated as the research subject field at the center of the natural sciences.
