DUERSON STOUT PSYCHOLOGICAL REVIEW COMPANY PRINCETON, N. J. AND LANCASTER, PA. AGENTS: G. E. STECHERT & CO., LONDON (2 Star Yard, Carey St., W. LEIPZIG (Koenigstr., 37): PARIS (16 rue de Condé) PREFACE The two articles which constitute the present monograph deal with the same general topic, the variations in function of corresponding parts of different brains. This matter has received scant attention in neurological literature, notwithstanding the fact that the anatomical variations have been extensively studied. The data recorded in the two articles point to a conclusion which helps to an understanding and to a conciliation of some apparent discrepancies in previous clinical and experimental studies of cerebral function. The theoretical discussion which is given is, however, not due solely to the work now presented, but in great part has been the result of previous personal observations and of various facts which have been recounted in clinico—and physiological-neurological literature. The experimental data of the second article were collected before the examination of the clinico-pathological data contained in the first article was begun. Many results of the experimental study could not be prepared for publication in the present article, and a number of duties prevented the earlier completion of the article as it now stands, but it is hoped that time will be found for the early presentation of the other collected facts which bear upon the same problem. Part of the first study was prepared for, but was not presented at, the conference on individual differences at Columbia University in celebration of the twenty-fifth anniversary of the professorship of J. McKeen Cattell. In the experimental part of the present work the author has had the assistance of and is under obligation to a number of former students, and of internes at the Government Hospital for the Insane, too numerous to mention separately. The major part of the assistance was given by Dr. J. Duerson Stout, now associate professor of physiology and pharmacology in the George Washington University and his name appears, therefore, on the title page. The research on the brains of the monkeys was made possible by reason of a grant to the author, for the purchase and maintenance of animals for the investigation of the functions of the cerebrum, by the Carnegie Institution of Washington, and for making possible this and other similar previous investigations the author here expresses his sense of obligation. For the convenience of the reader it may be mentioned that summaries of the experimental work appear at the ends of the individual sections of that article (see pp. 102, 105, 132, and 139). |
