The Apraxias

The apraxias have a special importance in the history of callosal syndromes, since it was the study of these disorders which led Liepmann to his remarkable analyses of syndromes of disconnection. The apraxias represent today that group of disorders of the higher functions which are best understood anatomically. The paper reprinted here represents a fairly elementary summary of the material in ‘Disconnexion syndromes in animals and man’. Since the publication of this paper I have had the opportunity to develop my ideas much more extensively. A much more complete discussion will appear in a future publication.
