APPENDIX C 

 SAMPLE ANALYSIS OF NEUROBIOLOGICAL LITERATURE 



The following tabulation has the dual 

 purpose of (a) listing the media of publica- 

 tion available for neurobiological work; 

 and (b) determining current trends in 

 neurobiology by an analysis of the content 

 of a single journal (Journal of Compara- 

 tive Neurology) over three equally spaced 

 5-year periods. The data have been com- 

 piled under the supervision of the present 

 chairman of the Committee by several as- 

 sistants. They are accurate within the 

 scope of this survey without pretending 

 to being exhaustive. 



Table I lists journals with central in- 

 terests in neurobiological subjects, Table 

 II journals with marginal interests. 



Tables III and IV contain a breakdown of 

 articles published in the Journal of Com- 

 parative Neurology during the three 5-year 

 periods 1911-1915, 1926-1930, and 1941- 

 1945. Table III shows the general trends. 

 Table III-l gives data on total output. Table 

 III-2 on relative preoccupation with human 

 material, Table III-3 the relative topical dis- 

 tribution, and Table III-4 an index of cross 

 correlation with other fields, as derived 

 from the frequency distribution of biblio- 

 graphic references. 



In Tables IV-A, B and C, an attempt is 

 made to show the extent to which methods 

 of different neurobiological disciplines have 

 been used singly or in combination in each 

 of the 5-year periods; systematic changes 

 in these figures are indicative of collabora- 

 tive and integrative trends.
